Cannot Get a Preview by clicking a Thumbnail

I have not had this problem before but in 8.5 I can’t get a preview in the way I expect to. I see a message saying the storage location is unavailable.
The database configuration page show the correct path C:\users\Mypc\One drive\pictures
and Preview is set to on.
I must be doing something wrong or not doing something.
Can anyone help? I’d appreciate it.

What app are you having this problem in?

Sorry! It is Digikam.
