I’ve was having the same issues that are posted on this thread. But after some digging and, I discovered that two dependencies were not installed. I installed them manually with:
sudo nala install libqt5gui5-gles libqt5quick5-gles
reboot
NOTE: This unistalled some packages that I guess may have been contributing to the crashes.
I am currently testing Discover after this install and I am not getting the crashes that I was before. I will continue to test this out and report back whatever issues that I have. I hope that this helps. I am currently running Linux Mint 22 with KDE Plasma (I know some in the dev community will think I’m mad…lol) but so far Discover was the only issue I was having. Please reply with any updates on your current situations. And again, I hope this helps
