Assertion failed with Steam Audio

Hi all.
I have this error the first time I enter Game Mode after starting the Unity Editor. In this case, the new input system also stops working. The same error occurs without a new input system.
After exiting the game mode and entering it again, everything starts working normally.
Unfortunately, when I build a project, this error is constantly present when starting the builded game.
This error disappears, when SteamAudioManager script removes from the scene.
Any ideas?

Unity 2020.1.7F1, Steam Audio 2.0 b18, Win10 19.09 64bit

Looks like the Steam Audio Plugin is still in Beta. Maybe it helps if you use a previous version? Although I can only see this version… Release v2.0-beta.18 Release · ValveSoftware/steam-audio · GitHub

Same problem for me… I have replaced the steam audio plugin by the Oculus audio spatializer.
…And that fine.
