"Capture One Can't Process" error on startup

I've been getting an error upon opening Capture One that it can't process, and to try restarting the app or computer. Neither has fixed it, nor has reinstalling, wiping preferences, batch queues, running OnyX, making a new admin user account, uninstalling various other apps that might possibly interfere, and probably a few other things I'm forgetting. Has had me absolutely tearing my hair out. This is on the latest MBP M1 Max, running Monterrey 12.2.1, with the latest C1, 15.1.2. Luckily have a backup laptop, but would like to use this new one, any help would be appreciated.
