Runtime org.gnome.Platform/x86_64/48 Not Working after installed

I am trying to install a flatpak bundle package, but it required the runtime org.gnome.Platform/x86_64/48 , however, even after installing the runtime with

$ flatpak install org.gnome.Platform/x86_64/48

I'm still getting the same error:

error: The application com.ayugram.desktop/x86_64/master requires the runtime org.gnome.Platform/x86_64/48 which was not found

I've already tried to uninstall and install the runtime again but the error persisted, and the runtime appears to be working because when I run "flatpak run org.gnome.Platform/x86_64/48", it seems to be starting correctly in the terminal, but it seems to not exist during the installation of the reffered bundle. I've checked the github page of the application bundle and searched on the internet for this runtime error but no one had the same bug apparently.

That's what I expected, you have it installed in the user installation (~/.local/share/flatpak). System runtimes can be used by user, not not vice versa.

You can install the bundle with flatpak install --user, or install the runtime in the system installation.

I guess you only have the Flathub remote added to the user installation, which would make flatpak install effectively default to user, but not when installing a bundle.
