Scared - do I have a virus?

Hi everyone,

I have a Windows 10 PC. I am currently having some serious issues - I cannot open settings, the windows menu doesn't work, the taskbar is malfunctioning (can't right click most things), I can't search in the search bar, my OneDrive stopped syncing and gives me an error every time I try to sign in, and I can't change network/wifi settings.

When I try to open settings manually, I get the error message "This app can't open
There's a problem with ms:resource-DisplayName. Refreshing your PC might fix it. Option to refresh" (I am afraid to refresh without knowing what I'm doing).

However, I can use my antivirus as normal and I did a full scan (nothing found), I also scanned with MalwareBytes and nothing was found. Restarted my computer about 10 times, rebooted in safe mode (same problem), tried cleaning up my disk.

I don't visit illegal or dangerous sites and only use private wifi. I have not done anything different in the last week with my computer OTHER than watching Hulu with a VPN (I have used this VPN for years with no issue). The other issue that started this week was the "Clearnview Sync" popup supposedly from my antivirus (https://community.norton.com/t/norton-error-message-re-clearnview/366222) which I just exited and ignored. I haven't gotten those popups for a few days now.

If anyone else has had/solved this problem or knows what's going on, it would mean the world to me if you could share!! Thank you so much :)
