Unity Editor : walls overlapping error

[ClariceHilton]

When loading the main scene with oculus link in the editor I get the following error:
It appears some of your walls overlap, are the walls intersecting? Please recreate your room in Settings. (in headset)
Error parsing walls, are the walls intersecting? Index was outside the the bounds of the array.

It seems that it can't access the fourth corner information and it throws an exception.

I am on quest 2, Unity 2020.3.18f1.

The official app release has no problems and I have tried redoing the set up.

Hello, is this error still occurring? Does "Clear Room Setup" fix it? (not just redoing Room Setup)
