madeingermany: Since about a week ago whenever I start GOG galaxy on my Mac, it displays an error popup

GOG galaxy - Error
Connection to Communication Service was lost and could not be restored! GOG Galaxy will now shutdown.

All I can do is press OK, then the client will load and shut down.
The same error is present when I start offline (without active network connection).
I also deleted the folder under /Users/Shared/GOG.com and reinstalled, but the same error persists.

Please note, this an M1 Macbook Pro, on Ventura 13.4 - however, the client worked fine a few weeks ago.

I think this is the relevant log entry. I would attach more, but you only allow images.

cousta: Do any of you have multiple macOS user accounts?

HYP3R_STYK3R: I'm having the same issue on a Macbook Pro M2 and I do have multiple user accounts.

joho11x: same problem on iMac 2017 Mac OS Ventura
/Users/Shared/GOG.com/Galaxy/redists/GalaxyCommunication
terminal command solve problem for me

cousta: Here's what works for me on macOS:
1. make sure that any other system account is logged out
2. open a terminal and run /Users/Shared/GOG.com/Galaxy/redists/GalaxyCommunication
3. launch GOG Galaxy

GalaxyCommunication will immediately exit if any other account is still logged in. I assume it's a poorly thought-through attempt to prevent GOG account sharing.
