Discover GUI will not load, although process loads. It can be made to work if passed to strace.

For several days, I cannot use the Discover software app. (plasma-discover). Clicking the icon results in a brief animation on the icon, then nothing. Single or multiple attempts fail to load the screen, but they show up in System Monitor.

If I use strace plasma-discover from console, then the entire Discover software does load! It works fine thereafter. But once closed, will not work again unless passed to strace again.

Nothing significant that I can recall was done to cause this, and many other individuals online have the exact same problem.

today I received a notification that updates were available. I tried launching via strace - which previously worked consistently - and this time, nothing happened - not even loading into System Monitor. I will reboot in a while and see what happens then. So this breaks the consistency previously experienced.

UPDATE: after a reboot, it loads fine via strace.
