Cannot launch timeshift on wayland

[MrDisguised]

Describe the bug I am using arch linux (with hyprland window manager) and I cannot launch timeshift. It worked last week but now it is not working anymore.

To Reproduce Steps to reproduce the behavior:

1. Try to launch timeshift from a menu launcher like rofi.
2. GUI polkit authentication agent pops up.
3. Enter the password for ur pc and click on next.
4. Timeshift doesnt launch.

Expected behavior I expected timeshift to pop up.

Screenshots If applicable, add screenshots to help explain your problem.

System:

• Linux Distribution Name and Version: [e.g. Ubuntu 16.04] - Arch Linux x86_64
• Desktop [e.g. MATE, XFCE] - Hyprland
• Application Version [e.g. v18.8] - Timeshift 23.06.2

EDIT - When I try to launch timeshift I get these errors -

[rounak@archissexy 02:17 ~]$ cat /usr/share/applications/timeshift-gtk.desktop | grep "Exec"
Exec=timeshift-launcher

Having the same issue with KDE/Wayland on Arch. Recommended workaround above fixed the issue for me.
