Document I have tried this with

This is the document I've tried it with (but I've had the issue before). Btw, JPEG export works without a problem.

ZIP with the suspectedly corrupt image (see comment)

ZIP file of the suspectedly corrupt PNG file, as I couldn't attach it directly. I suspect the PNG file is actually empty (as Bugzilla told me the file is "either ... or empty").

Looks fine for me:

@m.a.riosv

Interesting... Either the problem only affects my version, or there's a problem with my machine...
Comment 5 m_a_riosv 2023-11-19 01:25:37 UTC 
On Windows, got Add/remove, and select repair for LibreOffice.

@m.a.riosv
I've done as instructed – I repaired my LO installation and restarted Windows. I then opened my document again and tried exporting as PNG. The issue persists. I've looked into the files using a text editor (N++) and found them to be completely empty. The issue also persists with another document.
Comment 7 linus.sturm.github 2023-11-19 11:49:39 UTC 
I've just updated LO to the newest version (7.6.2.1), and the issue is gone. Apparently, this only affects the version I was using before (7.5.3.2).
Comment 8 Horst Schirmeier 2023-11-19 11:57:11 UTC 
Cannot reproduce with LO 7.5.8.1 on Linux x86-64, so this is probably Windows specific or specific to LO 7.5.3.x?
Comment 9 m_a_riosv 2023-11-19 13:43:56 UTC 
Then lets closed it.
