Welcome to the forum @Mickhawo
Does “Changing to “required” to continue” stick around, or happen on further runs (i.e. temporary change)?
Editing an existing backup then Options screen 5 Advanced options is a permanent method, if required.
Note the note that snapshot-policy requires administrative privileges enabled. This is sometimes awkward.
Autostart as Admin is the most recent discussion of this. Another option is to Install Duplicati as a service.
Before you were on OneDrive v2, were you on a Storage Type where you set username and password? Duplicati is sometimes not good at clearing these when Storage Type changes, but on the Destination screen 2 to the right of Backup Destination you can use the three dot-menu to manually edit out extras.
