there is a report, I do not know if this information will help to understand the problem ...There's no need to manually download platform files, the editor does it.On what hardware are you testing? There should be a crashlog if it's crashing.
Alright, the shader is the problem, metal needs all varyings to be named the same in fragment and vertex. So just go to fourbit / Vertex and replace uvVarying with texcoord in the 2 locations.
