Lost files after upgrading to macOS Catalina/Big Sur, help!

Hi all, after recently trying to update to macOS from Catalina to Big Sur, my entire hard drive has been wiped. Nothing on my desktop, documents, mail, folders, etc. and the files I used most often all disappeared. The applications are there but that's it. I search for Trash, but no luck. Very annoying.

Solution 1:Check another folder
This had happened in macOS Catalina update last year.

So, you can go to this folder to check if you can find those relocated items after macOS Big Sur update as well.
Solution 2:Restore lost data from Time Machine Backup
When it comes to restoring some of those files or your entire Mac, Time Machine app makes it easy. But this method works well only if you have Time Machine backups. You can try the following steps to see if you can restore lost data from Time Machine Backup.

Step 3: Use the arrows at the bottom and timeline on the left to browse the backups.
Step 4: Select the files or folders that you want to recover and click Store.

Potential problems with macOS Catalina/Big Sur upgrade
Whether it is a beta version or a public release, the operating system upgrades or updates were designed to go smoothly but things always didn't go as what you have expected. It's possible that you might get into more troubles than the previous macOS has as a whole. Here are some potential problems after macOS upgrades.
Case 1: macOS Catalina/Big Sur won't download
The most common problem is that users fail to download the upgrades of macOS Catalina or Big Sur. This is because a lot of people are trying to download the new macOS 11 Big Sur at the same time. Meanwhile, downloading may also fail if you don't have a reliable internet connection or enough storage space available on your Mac. If you have tried several times but macOS updates still won't download, here is what to do exactly to fix this issue:
Fix 1: Clean App store and download cache
Go to Finder and press ⌘ + Shift + G. Locate ~/Library/Caches/com.apple.appstore and empty this folder. Then reboot your Mac and try to download macOS Catalina upgrades again.
Fix 2: Check the internet
To check the internet, go to Apple menu and then click on System Preferences. Next select Next from the Control Panel. You can try to switch a Wi-Fi connection to an Ethernet cable in order to ensure your internet connection is as stable as possible.
Fix 3: Check the RAM (memory) and available storage
To check whether your Mac has enough space to download the new macOS Big Sur, you need to click on the Apple menu on the top left of your screen and then select 'About This Mac'. Make sure you have less than 4 GB of memory. Then click on the Storage tab on the same window. You will see how much storage has been used and how much free space is available (make sure you have at least 16 GB of free disk space). If your computer doesn't have enough space, you can add more memory or free up as much as disk space as possible.
Case 2: macOS Big Sur won't install
The macOS Big Sur installation stops at 99% loading bar and won't move forward? This can sometimes point to a compatibility issue. From the preview of macOS 11 Big Sur, you can ensure that your Mac is actually compatible with Catalina
Fix: Check if your Mac can run macOS Big Sur
Firstly, you should check your Mac model and make sure you have a Mac that can run macOS Big Sur. You will see your model specifications from the a list of all the Macs that can currently run macOS 11:
- MacBook models from early 2015 or later
- MacBook Air models from 2013 or later
- MacBook Pro models from 2013 or later
- Mac mini models from late 2014 or later
- iMac models from late 2014 or later
- iMac Pro from 2017 and later
- Mac Pro models from 2013 and later
Moreover, the new version cannot be installed onto an encrypted volume unless it's already in the APFS format. Last but not least, if your Mac has macOS 10.10 or earlier installed, you must first upgrade to macOS 10.14 Mojave or High Sierra before upgrading to macOS 11. If unfortunately, your Mac computer doesn't support macOS Big Sur, you should not upgrade or you can downgrade to the lower version.
Case 3: Apps freeze, crash or quit unexpectedly after macOS upgrade
App crashing after a macOS update is related to app incompatibility issues after a macOS update. This issue can mostly occur when the developer of the app hasn't released app updates compatible with the new OS requirements, or when the user hasn't installed the released app updates.
Fix 1: Force quit and restart the app
You can quickly fix a frozen and unresponsive app by forcing it to quit. Click on the Apple Menu. From the drop-down window, select the Force Quit option, choose the name of the App and then click Force Quit. After that, simply restart the app and see if it runs normally.

Fix 3: Uninstall and reinstall the crashing app

The last solution is to completely uninstall an application. This operation is more than just dragging and dropping the app in the Trash. You have to delete all of its preference files.

Open Finder click Go in the menu bar, hold down on the Alt/option key to bring up the Library option and then click on it. Search for the name of the application and the name of the company that created it.
Make sure you have deleted all of them. After completely uninstall the app, download and install the update again.
Case 4: Mac runs slow after macOS update
It's possible that you make the macOS update, but the system runs slow. The first reason could be that your Mac has too many programs that automatically run when your machine boots. It is also caused by the almost full startup disk on your Mac, leading to the slow performance issues. Beyond that, if you are using a mechanical hard drive or fusion drives, chances are your Mac will take much longer to start up.
Fix 1: Disable unnecessary login items
Click on the Apple menu on the top-left corner and go to System Preferences >Users & Groups. Click Login Items on the top of the window. Select the apps you don't want to open automatically and hit - option.
Fix 2: Free up the startup disk space
If you check the storage of your startup disk and find it is almost full, you need to make room for getting macOS Catalina running efficiently.
Fix 3: Replace your old hard drive with a new SSD
If your Mac has a spinning hard drive or fusion drive, the only fix is to swap out your old hard drive with a new SSD.
Case 5: Mac computer won't boot after macOS Catalina/Big Sur update
If your MacBooks and other Macs won't turn on after macOS Catalina/Big Sur update, the problem might be caused by a lack of power, some issues with Power Management System, corrupted files system of the boot drive, etc.
