Here too.

At the end I can see:

But I have to say, what Ubuntu delivers here is embarrassing. Snap Store is one piece of crap. Things that do not work here on 22.04:

1) Snap Store not starting right now
2) Snap store not finding any software when doing a search (had the problem before. but now 1)
3) Installed apps do not show up until restarting the computer or doing some refresh via terminal
4) The search logic doesn't seem to be as good as on snapcraft.io. It just doesn't find stuff. (But now 2)

Just embarrassing.

I have the same issue, I run snap-store on the command line and it displays me this message "Violación de segmento (`core' generado)", it says "segment violation ('core' generated" maybe there is a bad configuration on the snap packaging related to the base, I don't know, I'm going to search for different solutions.

Al right, I run the command "sudo journalctl --since=yesterday | grep snap-store" to see if it displays more information instead of just displaying "segment violation" on the terminal. the command displayed this:

I've noticed that it says error in a library, specially the libxmlb.so.2.0.0 library, I think that can be the cause of the problem, the library is broken and needs to be updated, I don´t know what else can I do, since I don't have experience about snaps, hopefully that information helps the developers to find a solution.
