when i choose a pdf to sign, click the sign document button and choose my qualified x.509 certificate and again click sign button in the dialog the dialog with all available certifications disappeares and a dialog where it should be visible that the document's been signed by xyz is empty. the document is not signed at all.

that feature works great in linux (gentoo) but is stopped working in windows 11 about 3-4 months ago. it does work neither in latest 24.x version not in 25.x version in windows 11.

Do you mean that it worked in version 7.6? Or that it worked in version 24.2, but then one day it stopped working without any updates occurring in LibreOffice? If the first, you can bibisect it:

If the second, then it can be something in Windows itself.
