Lightroom 9.1 wont launch windows 11

When I try to open lightroom the loading screen opens but I can't get past it before it stops responding and I get a error initializing lightroom assertion failed pop up. I've restarted, uninstalled and reinstalled, everything is up to date I dont know what else to do.
