Thanks for the reply - I've tried with crossplay both on and off already, and already only use windows defender, no AV, and I don't normally use any VPNs, those were just a reccomended solution. I added a screenshot and a text file of the dxdiag as I wasn't sure which you'd need, but hopefully one of those does the trick. I'm not great with tech stuff so let me know what to do from here if you can, thanks.
Also for extra context, I can't create my own session in multiplayer - it just says "Creating session" forever until you get bored, but I can see multiplayer/online times in time trial, both for steam friends and all other players. that might not be helpful but I thought I'd share just in case
