Unreal Engine 4.23 Released!

Hello,

I try to build an existing Project for Nintendo Switch and Xbox One. However since UE 4.23 this does no longer work. The build progress takes forever and at some point it crashes with an error Message like below.

I tried everything, deleted all textures and materials because of the mentioning of “Error: PNG Error: invalid block type” but nothing helps. Even if I try just to ship the game with an empty map it crashes.

A entirly new project works fine. So I crated a new project and copied just the most important files to the new one and it crashes again. As soon as I use any file of the old version, it’s crashing.

Does anyone have an idea? Other wise I have a massive issue as 3 years of work are more or less worthless.

I would suggest you guys create a support ticket, from looking at the logs it is getting an assert when its trying to package a texture (as mentioned) so somewhere, somehow it is trying to do that texture.

1. UATHelper: Packaging (Switch): libpng error: invalid block type
2. UATHelper: Packaging (Switch): LogImageWrapper: Error: PNG Error: invalid block type
3. UATHelper: Packaging (Switch): LogTexture: Warning: PNG decompression of source art failed
4. UATHelper: Packaging (Switch): LogTexture: Warning: Cannot retrieve source data for mip 0 of texture T_PR-9_Normal
5. PackagingResults: Error: invalid block type
6. PackagingResults: Error: PNG Error: invalid block type
7. PackagingResults: Warning: PNG decompression of source art failed
8. PackagingResults: Warning: Cannot retrieve source data for mip 0 of texture T_PR-9_Normal

And then it asserts...
