Crash when opening a project in Quartus 20.1

Question

I clicked open/cancel project a couple of times and then I got the crash below. It is a rare problem...

Is an exception like this posted to this forum in any way helpful?

*** Fatal Error: Unhandled exception

***

*** Below is the stack trace at the time the error occurred.

*** The lines beginning "Err Handler" represent frames relating

*** to generating this report.

*** The point at which the error occurred is somewhere after these lines.

*** There may be a few frames representing standard/library code

*** before the Quartus frames begin.

*** The search for the error should begin with the Quartus frames.

*** Unwinder: backtrace

*** Stack depth: 100

Before I go ahead and do this, I'd like to know if there's an official reference w.r.t. what libraries are required?

Note that the crash is occasional, so to me this is not indicative of missing libraries, it seems a bit like a shot in the dark.

Thanks!As this is an occasional problem, I need to upgrade to Quartus 20.1 in my daily workflow to be able to test this enough... It will be some time until I expect to have information as to whether these dependencies made a difference or not.
