Crash when project is reopened or upgraded
When reopening the attached project in Unity 2019.4.18f1or upgrading it to 2019.4.19f1 Unity will crash. This seems to be related to the metal API/Project Settings as if we use the automatic API option the crash does not happen. (Although the scene is rendered incorrectly)

Resolution Note:
so, if you first open with 2019.4.18f1 without the fix - it will generate bad shader code.
for these fixes we decided to NOT update shader importer version (they hit very specific edge cases and it doesnt sound important enough to force everybody to reimport their shaders).
so when you open in 2019.4.19f1 you STILL have bad shader code generated. You can solve this by clearing shader cache
either from menu "Assets->Clear Shader Cache" or manually killing Library/ShaderCache and Library/ShaderCache.db
