Hello, after i quit dota for 2 months i started playing again, now i get a "freeze" at the first game im playing(can't press keys, music stops), however when looking at the task manager, it says that dota is still running, however will freeze when trying to close dota with an error message Apphang1 as far as i remember. curiously after it froze once, i can play as many games without a freeze occuring again. It normally occurs at the 10-30 minutes.
I've already updated my Graphics card driver, reinstalled dota, checked integrity, also it doesn't seem to be a cpu or RAM overload.
i have no such problems at other games, at least for the moment it didnt occur anywhere else

If you have any hints or a solution thank you for your help
