Kopia UI wont launch (GTK error code)

Support
1

I get the following error code when launching Kopia UI (linux - Zorin OS). It fails to load by all launch methods, but I can see an error code when I have the terminal open and run

kopia-ui

Checking for beta autoupdate feature for deb/rpm distributions
Found package-type: deb
(process:12463): Gtk-ERROR **: 09:38:12.709: GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported

This problem started after my computer froze (I believe it was a hardware issue) and I then I chose to upgrade my motherboard Bios as I believe the crashing is part of Intel’s nasty defective chips. After the reboot, my Nvidia drivers were messed up and I uninstalled them and reinstalled the drivers. So I am not sure if this plays into the Kopia issue or not. I tried to purge and reinstall Kopia UI but there was no change in the problem.

EDIT:
Trying the following does not work:

kopia-ui --gtk-version=3

kopia-ui --gtk-version=4

But this does but Kopia does not stay launched. It closes/crashes a few minutes later and cannot be relaunched this way.

kopia-ui --gtk-version=2

Please help.

There’s a github bug ticket for this here: Kopia UI 0.20.0 fails to launch on Ubuntu 24.04 · Issue #4589 · kopia/kopia · GitHub
The contributors are expressing dismay with the Electron framework used to make KopiaUI a desktop app. I like the recent suggestion of just building it for the browser and letting it be a web UI, but TLDR: at the moment’s there’s no fix.
Downgrade to v0.19 and do not upgrade until a fix is mentioned in the changelogs. :folded_hands:
