Value cannot be nul (paramether 'path1')

Whenever I try to press launch game, the button goes black and the only thing showing in the output is something about 'path1' when verifying something about live. I am not an expert, I am new too so I got no idea.

I checked and the path is correct, also pressed select folder and selected again, but it still doesn't work, same exact error

GamePath has a value set to the correct folder

Got a new error which is:

[2023-09-05 13:39:06][Exception]Access to the path 'D:\CJE\Escape.from.Tarkov.v0.13.1.3.25206-P2P\Client.0.13.1.3.25206\Aki.Launcher.exe' is denied.
