ONLYOFFICE shows a blank screen when opening documents - 2024

[AlterNezKo]

When I double-click and open a document from the file manager, ONLYOFFICE displays a blank document. This does not happen if I open ONLYOFFICE first and then open the document. Moreover, it happens both in its .deb format and in Flatpak.

Operating System: "Debian 12 Bookworm".
Onlyoffice 7.5.1.23 (Deb - Flatpak)

P.S: This is a problem that also occurred on Lubuntu 18.04. But I didn't have it on Linux Mint 21 or LMDE 6.
