I tested several things: DirectX12 + Texture Streaming, Compile an launching the game = Crash DirectX12 + Untick Texture Streaming, Compile an launching the game = Works DirectX11 + Texture Streaming, Compile an launching the game = Works Build an old backup, with DirectX12 and Texture Streaming, it works. So there is something related to texture in my level. The solution is to resolving conflicting material GUIDs, and there is a free plugin for that! Perhaps the guid fixer can help? Could be duplicate GUIDs across levels causing material identification errors to where they are supposed to be. Not long ago paragon character imports were broken due to duplicate guids of material collections, so could be a similar case. --- _[View the full topic](https://forums.unrealengine.com/t/texturestreaming-crashes/1860550)._
