I upgraded to Windows 11 recently, and now my computer is basically unusable. The search bar isn't working, Task Manager is unresponsive, and I can't even find wt.exe. Furthermore, the troubleshooter and settings won't open, and I can only open files in specific apps, like having to use Paint just to open photos. I'm also having issues with Alt-tabbing not working. On top of that, I'm getting errors like "this file cannot be accessed by the system" when trying to open certain applications. I'm really at a loss here—any advice on what I can do to fix this?

Totally agree—it feels like Windows 11 has more issues than benefits right now. After my install, things just got worse over time. Hope you can find a fix!
Try running these commands: open Command Prompt as an administrator and execute the following: `dism /online /cleanup-image /restorehealth`. After that, run `sfc /scannow` to check for system file issues, and don't forget to reboot!
It sounds like your Windows installation might be corrupted. First things first, make sure to backup any important data. Then, consider doing a fresh installation of Windows 11 to sort out the mess.
You'll want to backup your important files and then create a bootable USB with Windows installation media. You might need another device for that. After reinstalling Windows, check your BitLocker status and consider turning it off if you're not using it. I feel you—Windows 11 has been frustrating for many users. It's a bit of a downgrade in some aspects!
