PDF to PDF/A-2 conversion creates dark page

Hello!

When input.pdf (2.3 MB) is converted to PDF/A-2b using Aspose.PDF 23.11, page 3 of the resulting output.pdf (2.2 MB) is almost completely black.
Later I tried the conversion using Aspose.PDF 24.2, but then it gets even worse, page 3 is black and page 1 and 2 are faulty too: output_24_2.pdf (2.2 MB)

What is the problem with this pdf?

Kind regards
