Check the \bt folder, are there any files?
If there are not, follow the steps below. If there are, go to Repair section
Try disabling your antivirus and then try to open a new beatmap. Does it work now?
If that didn't work,
Your osu! Might be having trouble with permissions
You can go to settings and click on the
Repair folder permissions option like so,
After that, move out the .db file again
If that still didn't work,
Try moving osu! To another location, fix permissions then move out the .db and \bt folder
