I don't know what you are looking for, and think, I cannot really help you.

The specification of the binary format is in [MS-ODRAW]: Office Drawing Binary
File Format
https://docs.microsoft.com/en-us/openspecs/office_file_formats/ms-offfflp/6ae2fd93-51fc-4e75-a54a-1b175c627b51

The shapes in question are legacy "text box" shapes in MS, German "Textfeld".
Those does not exists in modern docx.

OOo2.4.3 opens the file without problems, OOo3.2 crashes. The texts are legacy
rectangles there, not custom shapes and not frames. They are anchored "at
character". I see only three custom shapes, one for the rounded rectangle at
the top, one for the rectangle with text UNIT PLUS in the middle, and one for
the last rectangle at the bottom. The other lines are single lines.
