"MRUK couldn't load any scene data" in SDK v65

[robk.spacialxr]

• I'm using Unity version 2022.3.29f. 
• My Meta Quest Link has "Spatial Data over Meta Quest Link" set to true.
• Using SDK v64, I was/am able to load scene data in editor. 
• Using SDK v65,  I am not able to load scene data in editor and receive the standard error:

"MRUK couldn't load any scene data. Scene capture does not work over Link or XR Sim.
If using Link please capture a scene with the HMD in standalone mode, then access the scene model over Link.
If a scene model has already been captured, make sure the spatial data feature has been enabled in Meta Quest Link (Settings > Beta > Spatial Data over Meta Quest Link).
If using XR Sim, make sure you have a synthetic environment loaded that has scene data associated with it."

We also have this issue on 2/3 of our machines. Any luck finding a solution?

Sadly, no.  We're 3/3 on our machines.  I'm surprised it works for 1 of your machines at all.  Maybe there's a clue there?

I had hoped someone from Meta might answer this...

same. I have to change the SDK back to v64(in the unity package manager), and things went back to normal.

same happened to me today, but it was working fine before.

workaround solution : 
-in your headset remove all spatial data (parameters > physical space > space configuration )and redefine your room again with walls and furnitures.
works after that.

sidenote : this usually happens when the headset loose the guardian and you have to redefine it.
