Bug / Crash NullReferenceException Blueprint Edit

[brootas]

Hello,

When I create a Blueprint, I'm able to Generate it, but when I click Edit, I get a NullReferenceException that repeats every few seconds, and the scene that opens is empty. I've switched to the Default layout, and that didn't fix it. I switched projects, tried again, and had the same issue.

I'm using MacOS Monterey 12.5.1, and Unity 2022.2.0b10.

P.s. I found a similar thread by GinHuang, and even though it was not quite the same problem, I downloaded the patched 'ObiSkinnedClothBlueprint.cs' with fingers crossed but it did not resolve my issue.


Here's the error:
