Locking failed pop-up box

whenever i click on Lock Vault or Eject Vault i will get his pop-up box notification.

i am using windows 10

Also, when this happens, is it bad to force quit cryptomator? Would it result in bit rot?

Locking a vault (and unmounting the virtual drive) is performing this command:

The force unmount command is right below. This is basically all what Cryptomator does. If the unmount fails, Cryptomator gives you the option to force unmount the drive.

Cryptomator doesn’t know the reason why the unmount command fails but it’s probably due to some process still accessing the drive. If you’re 100% certain that you are not actively interacting with the vault (e.g., copying a large file), it’s probably safe to force unmount the drive.
