Can't export this file because of PNG file invalid

[MDTC]

I have multiple files which are composed the same way with the same pictures and files. Just in a different language. But when i try to export this Polish translated file, In Design seems to struggle with a file not being able to be exported.

Hm.

Check your Links panel.

It seems that InDesign has no access to the placed and linked image files.
