Operation Could not be completed Bridge

That message appeared while applying working on 8 CR3 photos this morning. To get rid of it, I had to do a forced shut down of my desktop. Nothing was new about the workflow and all my Adobe programs are up to date. Last week it was telling me I was running out of RAM, but this is not the case at all. My partner built the computer two years ago and checks everything periodically to make sure things are up to date.  Any ideas? Thanks.
