Unable to open start menu and settings Windows 11
I am on the beta channel of the Windows Insider Program for Windows 11 update but for the past 2 weeks, I have been facing issues with the start menu and settings. They don't open at all, I tried opening settings with CMD but I get "File system error(-805306367)". I did try reverting back updates using Advanced Startup Options Menu in Windows 11 but got another error. Couldn't find any other way to fix this. Need help ASAP. PS: No shortcuts related to Windows key work except Win+R.
