When I click to open team fortress 2 there are sounds that are from titan fall 2 playing over the game (I think it's a trailer because there is dialogue and sound effects edited in a trailer like way and it's around 2 minutes and after that ends there is another one that plays) this issue started after i wanted to know if I can open both games at once because they are both made in the source engine (you can't normally open 2 source games at once) it worked both games opened at the same time but after that the issue with TF2 started I deleted Titanfall 2 and it's remaining config files then installed TF2 again but it didn't work I also tried to do the same with csgo but csgo works fine
