Please help...

Getting

SteamVR Fail

a key component of SteamVR isn't working properly

When clicking More Info: You selected the issue: "VRApplicationError_IPCFailed"

On the same pc I did a native boot of windows 10 and wmr portal worked flawlessly.

Here was the spec it reported and as I said it works: https://drive.google.com/file/d/1otkwvH6pWh_IwbOEg-bnnYDpsvnPV6aK/view?usp=sharing

I also ran the powershell script https://drive.google.com/file/d/1U2Yd5otlcIEJDjslbciWqfcJ1q5mSX36/view?usp=sharing

It produced

According to the oasis driver guy:
A couple of other users went through this exactly and reached out to Valve, and it just looks like some particular architectures of laptops are simply not compatible with SteamVR native drivers, without any real solution. Based on some of my usage numbers, this could be as many as 1 in 5 laptop users. I unfortunately don't have any solutions to propose.
