After last update I cant join Valtan server

Hi, after the last update when I go to join Valtan, after about 30 seconds i get a message an error has occured. Exiting the game and it shuts the program down. I have the latest drivers, updated win 11, verified my local files on steam, ensured that its not blocked by my firewall but no change. I still cant join the server or play the game. No idea why as I have been playing without any issues since launch. Any assistance would be appreciated.

Using exitlag?

Yes I am using exitlag. I tried to start with exitlag disabled and didn’t make a difference. I’m re installing at the moment to see if it makes any difference.
