Tokodon exits when "Continue reading where you last left off" setting is set on and then clicking on the Load more button

Tokodon version 25.04.0 on Kubuntu 24.10 under Wayland.

I read posts from Fediverse on my Kubuntu desktop and on the iPhone or iPad Ice Cubes app at different times during the day and I’m having a random niggly little problem where Tokodon sometimes exits when “Continue reading where you last left off” setting is set on and then clicking on the Load more button. This seems to affect both the Flatpak and Snap versions.

I have cleared the cache from the Flatpak configs but it didn’t seem to make any difference and I have reconnected/reauthorised to the Mastodonapp.uk site, but again, no difference. It doesn’t have the problem most of the time.
I have tried running the flatpak from the command line (flatpak -vv run org.kde.tokodon), but nothing is printed on the terminal when it exits.

Is anyone else experiencing this, and does anyone have any suggestions on how to debug this in order to possibly provide a bug report?

I also sometimes receive the following error message. Again, any ideas?
