Try to remove Game.prefs - make a backup before

[Custos_StSp]

@magge
After deleting Game.prefs, it turns out to play 1 game, after which the error reappears.

The only thing I change in the game settings is 1920* 1280 60 and sound
P.S. it's hard to play without hotkeys

[magge]

Can you attach that Game.prefs - Thanks in advance

[Custos_StSp]

@magge
this file is after 1 game
Game_prefs.zip

Thank you, this helps to test it even more - I am sorry that you are affected by this issue, I know it can be very frustrating when it simply breaks all of a sudden. It is being actively worked on to fix it, the status can be followed here:

@magge
I did not change the language to Russian and was able to create a game for the 2nd time

@DEWOSTATOR23
не стал менять язык на русский и смог 2й раз создать игру

[DEWOSTATOR23]

@custos_stsp Сейчас тоже попробую

[DEWOSTATOR23]

@Custos_StSp создал с английским языком 4 игры с ботами и опять ошибка.
