"Assertion failed" on cooking for Windows

Hello everyone!
I’m trying to package a game for MacOS and Windows.
The MacOS build went fine and the .app is working.
But when i switch to windows it gets to a point where the output prints this:



Please help me, i have no idea where the issue could be.

Hi s.mancuso95,

Whenever the automation tool fails (as shown above) copy the entire contents of the Output Log and paste into a text editing program. Then search (Ctrl + F) for the word “error” to locate the Warning/Error Summary. The first few warnings under this header/title is typically what is causing your build to fail.

If you cannot resolve this yourself, attach and post the text doc that includes -the entire- output log. You may have to retry packaging to get this. If so, open your Output Log and right-click and choose “clear” to start with a blank log. Then package your project again and obtain a log from that attempt.

Thank you for the tip,

I scrolled everything but I couldn’t figure it out.
Tested everything on a new machine but with the same results… I post here the log so you guys can have a look:

Typically what I responded to before is accurate, however, not in this case. So it looks like the error is occurring when building textures, specifically after this line:

…So probably not the ShadowMapTexture2D but the next texture in line to be built. Check your textures to make sure they are all supported file types and powers of 2 (512x512, 1024x1024 etc.)

Also do a map check for each level and correct any errors.
