And it works on the last week build 20260418 too @VistaLover
Well, for the sake of testing while I have it on a ramdisk, I didn't notice that palefill stopped working, so I did the fix mentioned, changing strict compatibility to false on install.rdf, and while now can be installed and, I guess, works, on the latest build, 20260425 it still hangs/freezes, so the palefill availability is not the culprit of the hangs/freezes.
Why doesn't happen to you @roytam1? No clue.
Is just visit github.com/notifications and after load, freeze (unresponsive window to any interaction, except close).
I don't have the means to debug it.
