It has been found that under many circumstances, plasma-discover will not load if more than one backend is present. This was first discovered in plasma-discover 6.0 but the same code seems to be also present in plasma-discover 5.27.11. Bug fix is found at https://bugs.kde.org/show_bug.cgi?id=481993. For instance, if plasma-discover is loaded with just the packagekit backend, it will load. If it is loaded with just the snap backend, it will load. If it is loaded with both, the GUI will not load.
It's possible that, though tested, the fix in the aforementioned bug will not work as it would be a backport from plasma-discover 6.0. However, this seems unlikely as it's highly tested at this point.

[Test Case]
From the terminal:
* $ plasma-discover --backends packagekit-backend backend, snap-backend
* (will load normally)
* $ plasma-discover --backends snap-backend
* (will load normally)
* $ plasma-discover --backends packagekit-
* (will fail)
