My friend renistalled Valheim, and any time he tries to join a game, either mine or his, he gets into the world, then crashes. I've had him verify it, update his drivers and windows, and update direct x. he is running Windows 11, and I think that is the biggest issue, because it runs fine for me, our 2 other friends, and it ran fine for him before he updated to Windows 11.

What other options does he have for getting it to work? any suggestions are welcome!
