Hello ! I have this problem where if I open Team Fortress 2 and I get to the loading screen of 2Fort or some map the whole Steam freezes and I can't close it in any way so I have to restart my computer. I tried to get a answer on Steam Forum, but got no answer. I have heard that people had this problem before, every year few cases of this happens. I am not 100% sure what caused it. it started (maybe) when I was making a TF2 map for SFM, I had to move the map from my TF2 maps file to my SFM maps file since it automatically was created there. After that I noticed that my TF2 maps had the SFM map icon so I tried to run them with HL.exe. From what I have heard, for somepeople typing "-autoconfig" in launch options has helped them, but did not work for me. Also I heard that re-installing TF2 doesn't help. Any ideas what to do ?
