Purpose of community folder

By a crash do you mean a freeze up? I have had a few of those from time to time . Not sure why . Seems if I move my mouse or hat switch a little too fast it happens . I just upgraded my video card tho .
Not really that big a deal (tho it does kind of p me o when it happens) Not unusual for 2020 to do that to me. I just use the task manager and start over .
