SteamVR does not work after VIVE Business Streaming Software being updated to 1.06.6 from 1.05.1a .
The hand controllers of Focus 3 are not tracked by SteamVR and sometimes PC-VR software is not responding.
SteamVR also was updated to 1.21.5 BETA yesterday. However, the above issue is still not solved.
I made VIVE Business Streaming Software change back to 1.06.6BETA with switching in setup panel BETA-program ON.
And SteamVR works well with 1.06.6BETA .
