This is what has happened, in sequence:

I got an error on Calibre saying my database was corrupted. I hadn't updated Calibre in awhile, so I went ahead and uninstalled and installed the new version.

It still said the database was corrupted, so I restored from backup. Unfortunately, I had not backed up since sometime in 2018, so while a lot of my books showed up in the library, they weren't really there, and I kept getting database errors.

I decided to check a book I KNEW was on the backup, so I did, and got this error:

Error: unhandled exception
Critical Error: Failed to launch worker process: Traceback (most recent call last): File "site-packages\calibre\utils\ipc\server.py", line 239, in do_launch File "site-packages\calibre\utils\ipc\launch.py", line 394, in_init_File "subprocess.py", line 644, in_execute_child WindowsError: [Error 5] Access is denied

So I uninstalled and re-downloaded the file and installed again, and same thing. Calibre is completely useless to me.

I hope you can help.
