Hi and Welcome to the Community!
I recommend that you attempt to boot into Safe Mode:
It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. If you are successful at getting into Safe Mode, think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.

Hopefully you already have a good backup, as it's unlikely you'll be able to take one now.
Good luck and let us know!
