Well I checked the game.log and there are many strange errors.
WARNING: Unknown DirectSound speaker configuration 8. Defaulting to Stereo.
This can cause crashes while playing, please set your speakers to stereo
WARNING: UI layer has not been initialized.
WARNING: [C]: in function `GetFrame'
Never saw this error, but i guess when parts of the Ui fails, you will not see everything.
WARNING: ...ata\faforever\gamedata\lua.nx2\lua\system\import.lua(155): Error importing '/lua/maui/effecthelpers.lua'
WARNING: ...ata\faforever\gamedata\lua.nx2\lua\system\import.lua(155): Error importing '/lua/ui/game/chat.lua'
WARNING: Error running lua command: ...ata\faforever\gamedata\lua.nx2\lua\system\import.lua(155): Error importing '/lua/ui/game/gamemain.lua'
Then we have several gamefiles that fail to load.
Looks like they fail because part of the Ui is missing.

Hundreds of files that cannot be found from these mods.
Also the mod directory path is very strange with an additional directory array
There are also warnings from mod file validators.
(Some mods have build in file checkers)
The RNG AI is reporting that there is an additional file present in the mod and some bytes are missing
Total Mayhem is running, but the file validator isn't showing up
The Wyvern Battle Pack filevalidator is erroring out.
So we end up with many files that cannot be found due to wrong directories.
I can only guess, but that's the main reason the games aren't working.
Make sure there is no virus on the system and Windows is in good condition
check all game files (maybe reinstall)
remove and redownload all mods.
(Make sure you're not using OneDrive or similar)
