Does not start on F33/F34

Reproducer:

• install it on Fedora 33 through flatpak install flathub com.synology.SynologyDrive
• run it through the Fedora "desktop" icon, create a simple backup job and close it
• try to run it again through the "desktop" icon => nothing happens
• try to run it through flatpak run com.synology.SynologyDrive and see the error below
• try flatpak repair com.synology.SynologyDrive, uninstall & install => doesn't help

Error:

After running unset SESSION_MANAGER the Qt: Session management error is gone. BTW:

$ ll /sbin/udevadm
lrwxrwxrwx. 1 root root 14 Jul 20 19:04 /sbin/udevadm -> ../bin/udevadm
$ ll /sbin/ifconfig
-rwxr-xr-x. 1 root root 81392 Aug  6  2020 /sbin/ifconfig

The same happens on Fedora 34.

Fedora 34

The wayland and fallback-x11 sockets are enabled On Wayland, flatpak run com.synology.SynologyDrive initially produces:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

When launched with the QT_QPA_PLATFORM=wayland variable, the output changes to:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

It looks like a wayland-specific thing. Perhaps, the wayland platform plugin can be added in somehow? The AUR package for synology-cloud-station was patched to run on wayland, so it may be a good starting point: https://aur.archlinux.org/packages/synology-cloud-station-drive/

Setting the QT_QPA_PLATFORM=xcb variable as seen in the patch in the link above and having only x11 socket enabled solved the problem for me.
