Crash at initial startup

I installed the mod, as well as 2007 SDK and started the game up flawlessly; I went to change the resolution of the game and as soon as I did it crashed. I proceeded to start it up again but it loaded a black screen then appeared to minimize in the bottom right of my monitor and then close. I proceeded to uninstall it and reinstall it but it still gives me the same problem with the crash on the startup.

I’ve attempted to reinstall 2007 SDK and Mesa multiple times.

What are your system specs? (CPU, GPU, OS)

Try adding “+mat_forcehardwaresync 0 -dxlevel 90” to launch options.
