I’m getting gc. finalizer crash in ARM64 il2cpp android (oculus) build. When the build is release. If build is development crash doesn’t appear. I’m using unity 2022.2.14 with URP render pipeline.
A Fatal signal 5 (SIGTRAP), code -6 (SI_TKILL) in tid 15881 (GC Finalizer), pid 15851 (Inovepic.Future)

From the stack, it seems to have something to do with the ‘Inovepic’ (Inova EPIC?) third-party plugin/code. You might try testing with it removed (if possible) or contact them about it.
I’ve solved it and the issue indeed was in the code of Inovepic. The problem was in wrong disposing of an objects from scene on scene switch.
