Recently just came across the same error and after digging around I’ve found the solution.

Drag the clips in question (or the entire list of media if it saves you time) back into Pr, in a new TEMP bin that you will later delete.
Then go to the misbehaving clips and try relinking again: they will relink just fine without error, and you can delete the temp bin

Dragging the clips back into Pr somehow shakes up the app and tells it to give a fresh look at the files.

p.s. deleting the Cache folder/database didn’t fix anything, in fact it made even more random clips go offline.

Thanks, didn’t think of Color!
