Correct - packed textures does not work. I gave you a zip of a blend file with textures packed. - So unpack the textures into a “textures” folder - then set the texture paths to Absolute.
File - External Data - Make Paths Absolute.
Then do an export. - result no textures in the PackagesSources / …/ texture folder.
Here is my fix - it is a Kludge code fix - but it works for me.

EDIT: my testing has resulted in the requirement that - “ALL Textures in the blend file MUST be set to absolute” 4.2 has really messed up path joins etc.
