InDesign Crashes When I save a File

hi, InDesign keeps crashing when I save a file and renames my files to 'Testfile981xxxxx....' It has been like this for months but it has got to the point where it is unusable! I have uninstalled and reinstalled it with no change. 

When it crashed I get the errors attached.

I'm using a Macbook 15.4.1 Software and 16GB Memory, M1 Pro. I have uninstalled and reinstalled InDesign many times. I use idrive to save my files to, but have also started saving locally with no change.

Can anyone help please as I have a print deadline looming and I need to get the magazine I'm working on finished. Thanks
