Are you new to GPA? Is this the first time you've used it? I ask because sometimes uninstalling and reinstalling makes things work.
Do you have plenty of RAM and Hard Disk space? From the log, it looks like there may be an allocation issue, which could indicate a memory issue.
Also, which version of GPA are you using? 2020.3 is the newest.
My apologies. You are not new to GPA.
Did you change something before the GPAServer.exe started crashing? Like install the latest release - 2020.3?
