I'm having the same issue, and based on the log I think it's not due to the translation file... The error is thrown after the line
InitGraphicsMode: 5120x1440
And I'm having a similar issue, where the client fails with
19.11. 13:00:35.900 Initializing GameClass.
19.11. 13:00:36.020 InitGraphicsMode: 8560x1440
19.11. 13:00:36.027 KABOOOOOOM!!! Info:
19.11. 13:00:36.027 Message: HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect.
Do you think this may be due to having ultrawide monitors? My case is a bit more extreme in the sense that I have my GPU to combine 3 monitors into one...
