I have been trying to package my UE5 game for quite some time now but I keep getting this error and I have no idea why, can anyone help?
It wont let me post files on here yet so heres the link to the error log:
UATHelper: Packaging (Windows): LogTexture: Display: /Engine/EngineMaterials/BaseFlattenDiffuseMap_VT.BaseFlattenDiffuseMap_VT is marked for virtual streaming but virtual texture streaming is not available.
UATHelper: Packaging (Windows): LogTexture: Warning: Building texture with an invalid GUID: /Game/PaperAssets/Environment/NewTexture2DArray.NewTexture2DArray
UATHelper: Packaging (Windows): LogOutputDevice: Warning:
UATHelper: Packaging (Windows): Script Stack (0 frames) :
PackagingResults: Warning: Building texture with an invalid GUID: /Game/PaperAssets/Environment/NewTexture2DArray.NewTexture2DArray
UATHelper: Packaging (Windows): LogWindows: Error: appError called: Assertion failed: 0 [File:D:\build\++UE5\Sync\Engine\Source\Runtime\ImageCore\Private\ImageCoreUtils.cpp] [Line: 110]
PackagingResults: Error: appError called: Assertion failed: 0 [File:D:\build\++UE5\Sync\Engine\Source\Runtime\ImageCore\Private\ImageCoreUtils.cpp] [Line: 110]
Assertion failure is here (err, at the bottom), and one would assume the warning immediately before it is the problem (Warning: Building texture with an invalid GUID:).
I also included one log message above that though (it is one of many of the same message) which also looks a bit suss.
This reddit post is the same error, and was ultimately caused by an unused texture (?!?)

Edit: Presumably /Game/PaperAssets/Environment/NewTexture2DArray.NewTexture2DArray is not a legitimate file and was created by accident… assuming so, just delete and try again?
