Like the title says, game freezes when I start a private match, nothing to do except end the process.

Anything in the console?

I can't tell. Nothing responds, can't alt tab or anything. Have to ctrl+alt+delete, task manager is the only thing that works, have to end the process.

Try playing in windowed mode, maybe you can see some error dialog pop up.

OP, to get into Windowed mode press alt + enter .
