Can't add book / can't open database

I ran into this when trying to add a book to my library. The same error happens when I try to open an existing book in my library, but then the book does open.

calibre, version 5.21.0
ERROR: Errors while adding: Failed to add any books, click "Show details" for more information


----------------------------------------------------------------------
Failed to add the book: An Introduction to Machine Learning
D:/username/Desktop/Kubat2017_Book_AnIntroductionToMachineLearnin.epub
With error:
Traceback (most recent call last):
File "calibre\gui2\add.py", line 457, in add_book
File "calibre\db\legacy.py", line 334, in create_book_entry
File "calibre\db\cache.py", line 75, in call_func_with_lock
File "calibre\db\cache.py", line 1698, in create_book_entry
File "calibre\db\backend.py", line 920, in execute
apsw.CantOpenError: CantOpenError: unable to open database file

Any ideas? My database is not on a NAS, just a local disk.

Check that that entire folder has full rights (not just read only)
Note: your A/V might have blocked write access to your documents folder.

Calibre now installs NEW libraries into the level above, <your user name>
You could try and move it USING THE OS (Calibre NOT running), then use Calibre to link to the new location.
right click the Library icon: Create/Switch: USE EXISTING

Ah, you're right. It's the Controlled Folder Access on Windows 10. I enabled it last month and completely forgot about it. Thank you so much.
