Steam IL2 BOS Not responding

[Grobby]

Updated to W10 v 2004 on 25 Aug 20.

Since Il2 Steam is not responding. (Not shortcut, Nor Steam library, Nor from IL2.exe)

Disabled the audiodriver Nahimic 2 v 2.5.6

This seems to solve the problem.

Any computer Wiz has a better solution?

Is there a way ahead?
