How do I play TF2 with Manjaro (Linux, Arch Based)? - eviltoast

I switched to Manjaro, an Arch based Linux distro, knowing that the games i play are compatible with it either with proton or by being native to Linux.

As far as I know it TF2 is native to Linux, casual is supposed to work too with VAC.

But even then, I’ve been having lots of problems with it, with crashes (solved), VAC (“Your computer is blocking VAC” error message) , and using mods (Masterconfig).

Please tell me everything I’m supposed to know to play TF2, I would come back to windows 10 to play it, but I want to fix this above all things.

Thanks for your time.
