Can you perhaps provide stacktrace?

Attched (I think)

[martinrotter]

I see, does the crash occur everytime you do that thing or just sometimes?

[AndyM48]

Every time, no exceptions (as far as I can see)

Judging by this trace:

Thread 1 (Thread 0x7fffd3bc83c0 (LWP 25570) "rssguard"):
#0  0x00007ffff77117dd in ToastNotificationsManager::resetNotifications(bool) () at /usr/lib/librssguard.so

#3  0x00007ffff76dda2e in FormSettings::saveSettings() () at /usr/lib/librssguard.so

It seems to be the same issue as #1317, which was fixed by commit 3b19a66.

But the fix is not present in any release yet.

@AndyM48 Can you please test with the AppImage from development builds? Just to be safe, make sure to back up your RSS Guard data first.

[martinrotter]

Likely fixed by the release, if not, please feel free to reopen and provide additional info.
