Made From CrashReporter
To remain Glitter compliant logs can not be linked from Crash Reporter. Should you need logs you will have to get them from Crash Report.

Steps to Reproduce

1. Create a Lyra, 3P, or VR template project
2. In a content folder, create a 2DTextureArray 
3. Add Source textures via the dropdown menu (do not drag and drop from content browser)
4. Hit an assert

Source Textures can be added via dropdown menu.


Assertion failed: bIsRoutingPostCompilation == false [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\TextureCompiler.cpp] [Line: 245] Registering a texture to the compile manager from inside a texture postcompilation is not supported and usually indicate that the previous async operation wasn't completed (i.e. missing call to PreEditChange) before modifying a texture property.
