Premier generating generic import error out of nowhere

Updated to braw 1.7, working in a project after no problem, while editing, all of a sudden all braw media has gone offline. Multiple restarts and reinstalls, no luck.

I had this issue and what finally got my project working again was copying the footage to a different directory. No other changes and that fixed it. Very annoying and I'm not sure why it happened.

Thanks for the response- much appreciated
