As requested: New bug report for the crashes in bug 950270: Libreoffice with the gtk4 backend on Xfce with no gtk4 theme: Several dialogs immediately crash when opened: * Menu "File", item "Export as PDF" * Menu "Insert", item "Envelope" * Menu "Tools", item "Footnote/Endnote settings" Moreover, whenever I select "Help" / "Libreoffice Help" (F1) or press the "Help" button in any dialog, Libreoffice shows a dialog that help for my language is not available. When closing that dialog, libreoffice also crashes. All those crashes do *not* happen with the gtk3 LO Backend or the qt6 LO backend. Sorry, I can't help reproducing the crashes: I no longer have the gtk4 backend compiled into LO, and I no longer have gtk4 installed at all. But others have reproduced at least the "export PDF" crash, see bug 950270.
