I spent some time a while little back looking at some weird crashes on startup I was getting on Android.
Basically, some new materials I added would cause my project to always crash on startup, even though there was nothing bad about the materials.
Turns out it was crashing when the engine tried to merge some GC clusters while starting up.
So, I’m turning off [Project Settings → Garbage Collection → Merge GC Clusters] to let me run my project.
I saw a post about a similar problem over here but there doesn’t seem to be any followup. Is this bug being looked at?
