When I try to install something from Flatpak. it takes me a lot of time. Unfortunately when I finish waiting for that time. Any application I download gives me errors.
Could someone help me?

Have you tried deleting that runtime and any dependent flatpaks and reinstalling? Looks like there is something that’s a problem with the delta update so maybe reinstalling it will fix it.

flatpak uninstall --unused

sudo flatpak repair

So cleanup unused runtimes, and do a repair

The last command may take a while based on your observations during installation.
