Error message: Internal consistency check failed

OS:Windows 10
Duplicati version:

I just noticed one of my backups (User folder) hasn’t run since January 26th. It was running daily up until then. I set it to manually run and got an “Internal consistency check failed, generated index block has wrong hash” error message.

I have another backup running from another internal hard drive which is working fine.

Just remembered that’s roundabout when I switch BitLocker on. I guess Duplicati doesn’t work with BitLocker or, more likely, I can’t see how to get it to work with BitLocker.
