Playing with 3440x1440 Resolution

[Luchas]

I can login to server select, but when I select Green Server (for example) and then click play, it seems it tries to load, but encounters some kind of Resolution issue and goes back to launcher where you enter password. Win11 current, GTX 3070, AMD Ryzen 5 5600X, Dell 34" Ultrawide WQHD monitor

I tried on my other pc using a smaller monitor at 2560x1440 and I have no problems on that machine. Game loads fine. Win10pro, GTX 660 TI, Intel I5 4670k, Acer 24" monitor.

Seems to be an issue with transitioning on login. Has anyone found a solution for this?
