Exception on startup w/ Holographic Remoting

[fast-slow-still]

An exception has been reported during startup when running under Holographic Remoting. The exception is:

EngineException: Error in call to FrozenWorld.Engine: "FrozenWorld_ClearAnchors: (failed s_state) Library not initialized"

System configuration reported as: Unity 2020.3.15f2 World Locking version 1.5.7

Assuming FWE v1.1.1.

Just a bit more info from my side - I also noticed that I was able to get rid of this error by trying multiple things at different times:

• Restarting Unity
• Restarting Holographic Remoting on Hololens2
• Checking and unchecking "Null Subsystem In Editor" and then restarting Unity
• Opening a different project that uses WLT and running Holographic Remoting
• Doing nothing and coming back after several hours.

I was not able to find a consistent fix for this but based on the workarounds above - I suspect it could also be an issue of something that was cached not being able to be cleared.

I also get this error right before the "Library not initialized" error:

EngineException: Error in call to FrozenWorld.Engine: "hkAnchorGraphFracture::detect: (failed associationSlot < (sizeof(Bits) * 8)) [internal error 0x6DAC5CE2 in Base\hkAnchorGraphFracture.cpp line 150]"

Restarting the Unity editor has solved it every time for me.
