SU 2021 pro 21.1.332 won't open large file

SU 2021 pro 21.1.332 wont open large file, 100,000 kb and larger ? this started last week, please help

What is the file location of the saved file?

the files are on google drive, however I have tried downloading them to desk top and the issue remains, I get either a File could not open. or this does not seem to be a sketchup file

Did you save them there directly from SketchUp, or did you save a local original first? Saving directly to the cloud is prone to file corruption errors.

unfortunately I had never had issues so I use Google drive stream, so far it had worked great 2y but may have bitten me
