Unreal Engine version issue

[Liovovo]

There is an issue with the Unreal Engine version when a custom version is present. The problem is in the following line in Main.cs:
args += " -game=ue" + selectedGame.UEVersion;
For example, if the version is PUBG (PlayerUnknown's Battlegrounds), the option should be -game=pubg. Removing the "ue" resolves the issue.

I apologize if my explanation is unclear, as English is not my first language.
