Please READ what's happening: 

It's not Quickbooks crashing, it's Chrome, File Explorer or MS 365 Outlook that crash and close when logging into a company file.   

It is annoying, it is frustrating, and certainly counterproductive. 

You can read through the previous posts in this thread and see what people have tried.  Including your suggestion of uninstall and re-install.  One or more posts mentioned buying brand new computers and still having the same issue pop up.

Calling QB's tech support does nothing.

It's time to find a fix for this.
