Unable to launch the game on Xbox Game Pass

For some reason, CK III stopped launching on Xbox Game Pass. Even this morning, it was still working. Now I click on "Play" on the Paradox Launcher, it loads a little, then turns off. Does anyone have a similar problem? forum.paradoxplaza.com forum.paradoxplaza.com
Good luck with that!

And, there was an update to the Xbox app last night - I've had one report so that that fixed a won't-start issue like that, so make sure it's up to date.

There game will simply not run an any 2 core/CPU setup, I'm sorry. As MS provide no way for you to revert to older game versions, I'm afraid all we can do is hope then get that fix out real soon!

TheWxtcher said: If its possible I really think there should be a warning on the Microsoft Store, had I known there was an issue with dual cores I would have waited until the fix and then activated my Game Pass. I only bought it as it was £1 and now it's just going to waste as I'm unlikely to renew it for the full price. Just to save others the frustration.
It is a bug in the 1.1.x patches, it used to work under 1.03, and will be fixed. We don't put warnings up for situations like that FYI.

Sorry for the bug!
