I keep having this crash when trying to build all levels.

Assertion failed: StreamingTextures.Num() == StreamingTextureGuids.Num() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\Level.cpp] [Line: 1912]

Any idea whats causing it?

looks like its some kind of texture streaminfg or virtual texture error
sometimes migrating all the levels (just select all levels that are in the project and only the levels then migrate)
even if a texture is not actually on a level it gets compiled if its in the project, so sometimes that moves over only what’s actually in a level and can unhump it

there is a setting to “package engine and plugin content”
that content is inside the engine under private

Worked like a charm! Thanks!
