I'm getting this as well.
I'm on a new laptop, Mac Monterey. I did the TimeMachine and GOG wasn't working - fine, I had jumped ahead on which version of OSX I was using. I uninstalled, and then put a new version of GOG Galaxy. Everything boots up fine, but the moment I scroll, it flashes up the error message and shuts down.
I even deleted Galaxy and reinstalled it, and I still
get the error. Exactly the same wording, exactly the same timing, all of it.
I don't have any antiviruses or anything installed at the moment, no VPN, nothing.
Anyone know what's happening, or how to fix it?
I'm having the same problem. I was able to get Galaxy to open once by deleting it, emptying trash, restarting my computer, and reinstalling Galaxy. It opened once, I played for a while, closed it, came back a few days later to the same error. I just sent a trouble ticket to GOG support hoping to get some information.
