Fedora is Fedora and uBlue is uBlue, a separate project. Blaming Fedora for uBlue issues is like blaming Ubuntu for Mint issues.
And on Silverblue issues on updated happen from time to time. On immutable distros such issues won’t break the system unrecoverable, this is the whole reason for immutables, but there are no promises for lacking of issues.
And you are disappointed because you have encountered two different issues at once. But it is a purely random event, and I have not noticed any changes in frequency.
But saying about Silverblue, I think probably it doesn’t get much attention from the Fedora project lately, because few recent releases didn’t have any improvements either.
