it saves to google drive which is linked to my internal folders. I suspect that is the issue but this is a brand new issue as we have been working on these files and saving them to the same place for years
It very likely is the problem. It would appear that SketchUp can’t access the location.
It’s definitely not wise to be saving directly to or working on files saved to the cloud. Many users wind up with corrupted, unrecoverable files doing that. You should be saving files directly to your internal drive and only sync them to your Google Drive via Finder.
