I just had this problem today. I use GOG Galaxy so I can keep track of the time I have been playing in games but for some reason today it just kept crashing whenever I tried to load it. Tried reinstalling it and still had the same problem. This is extremely frustrating since I buy games off of Galaxy and want to access my collection. Can someone please help me with this? What should I do?

what antivirus do you use if any?

weird question I know but there is a problem with some AV's incorrectly flagging a key file as malware and removing it.
