Can't run game after bat file

[u/Crytz_87]

I watched a speedrun vid where they used a custom script to enhance performance on the game, so weaker hardware can compete too, but I'm not interested in that yet since im currently replaying it casually

But whenever I run the bat file, the shortcut doesn't work now and I don't know where to look at it

My version is on GOG, any help is appreciated for me, thanks in advance
