Dear experts,
After this lecture of deleting the starter folder the engine does not open anymore. Also other projects won#t open with the same error:
Assertion failed: GDefaultMaterials[Domain] != nullptr [File:D:\Build++UE4\Sync\Engine\Source\Runtime\Engine\Private\Materials\Material.cpp] [Line: 472]
I unzipped the starter folder backup and copied it into the Tank project content folder but that did not help either. Any ideas are highly appreciated.
Thank you, Peter
