Unable to start the game

I downloaded blackmesa and at first everything worked fine. But since I easily get headaches and become nauseated from games with head bobbing and motion blur, I wanted to see if I could turn it of and at the same time I increased the resolution.
After this, the screen went black as it usually does when u change the resolution of a game, but this stayed so I had to ctrl+alt+del and terminate the process.
I didn’t think there was anymore to it and that i just had to keep playing on the lower resolution but now when i try to boot the game again it just closes as fast as I run it. help please :x

go to here: C:\Program Files (x86)\Steam\steamapps\sourcemods\BMS\cfg
and delete config.cfg, now try playing.
