Calibre freezing when starting up

[plaxamate]

I've been having this problem since at least version 7. Running the Library maintenance doesn't do anything. The debug script is

calibre 8.0.1  embedded-python: True

And that's as far as it gets. If I click on the gui splash and force close, it typically works from then on until I reboot my computer. Sometimes it freezes also when I delete a book or a format. I have installed the latest version and it still does this.

Thanks!

Is the library on a local drive (not on a networked one)? Is any syncing or back-up program running in the background?

Reboot in safe mode and see if the problem goes away

Library is on a local drive and Backblaze is the only thing running sync. I cannot seem to get into safe mode. My encryption key for the drive works, but it doesn't give me the proper option to go into Safe mode. It just restarts after I put in my key. Is there another way to look into it?

What happens if you stop Backblaze before you open Calibre?

[plaxamate]

Same thing. If it helps, when it's on the initializing phase, it's really running the hard drive.
