[2023] Constant crash to desktop after a minute of gameplay now

Is this with a save/campaign that was started under a previous patch? If so, best to revert to that patch in the Steam Betas tab for this game, to finish it off.

Then you can opt out of that older version back to the current version, to start a new campaign.

All the best!  

Royal Court worked under the older patch so that should be okay. How the game reacts to the introduction of a new DLC part-way into a campaign I do not know though, that's a quite independent factor to the patch save compatibility issue. You could of course disable that DLC in our launcher or the Steam "Manage My DLCs" page.

Good luck!
