VtM Bloodlines refuses to run with the Unofficial Plus Patch

After installing the game with the UP+ I try to run it and every time I get the same error:

I have no fucking clue what to do, I just wanna play my game.

UPDATE!!!: I FIGURED IT OUT! What I did was I used the Lutris installer that was “GOG with Unofficial Patch” rather than “GOG + Unofficial Patch” and ignored the instructions that say to switch to the Linux runner, instead using Wine as the runner. Finally I set Loader.exe as the executable and also adjusted the directory and so on. Game runs perfectly.
