@dwarf it looks like qt 6.7 only recently went stable as part of https://bodhi.fedoraproject.org/updates/FEDORA-2024-c9a2438d21 . so I guess maybe that update got incompletely applied on your system because of telegram-desktop. same advice applies, remove telegram-desktop and run another system update. when telegram-desktop is rebuilt in rpmfusion you can reinstall it, or just use a flatpak as you said. sorry for the trouble!
