I try launching tf2 but it doesnt open the game not even an error is shown ,but It shows through steam that i am playing tf2 plus hl2.exe is open but tf2 itself doesnt launch.

I tried:
Deleting blob file.
Validating cache files.
Uninstalling steam +tf2 .
Updating all my drivers and windows itself .

Can’t find any solution in steam forums or etf2l forums .
Please help .
