Comment 4 for bug 1873388

There's not nearly enough information to troubleshoot or debug this issue.

The Trace/breakpoint trap (core dumped) error is curious but it doesn't give us any information to help find the cause of the issue.

I am also unable to reproduce the issue on a fresh install, though I do notice that when I run snap-store from the command line, I don't get the g-settings warnings which makes me think you've made changes to your system outside the Snap-Store.

Look for a log of some sort and report back.
