I am having a crash only on one specific scene in my AR Foundation Unity build with the following error.

At first I thought it was because I was missing the Environmental Probe manager in that scene (no). Then I thought perhaps it was because I was using a specific shader that didn’t use a _MainTex. But I use that shader no problem in other working scenes.
And then I built the scene with only a simple primitive and my UI and still received this error. After that crash the scene did open successfully, but obviously the problem is still there. The UI is the exact same as the other working scenes.
I can’t find out much about this specific error: TexturesMetal::AddCreatedTexture - only that there may be this bug with GLES3 and PVRTC textures - but they aren’t present in the most recent build.
The scene works perfectly in Android - it only crashes in iOS.
Any ideas? Full report below.
