and the above (as shown) works fine, on the other side I’m only getting a blank, blocked window and (eventually, when I quit) a crash report, if I try to launch it from super > Activities > typebox > click
So, you have To do installed also as an rpm.
The icon in GNOME overview is launching it. Probably. It’s strange, I expected two icons (one for the flatpak, and one for the /usr/bin/gnome-todo one) but who knows.
Try to uninstall the rpm.
I’m coming from gitlab gnome, where I asked a feature for the calendar and discovered that they manage the tasks with this separate app, unfortunately. I’m afraid they will close my request as out of scope.
Have you looked on bugzilla if someone already reported the issue for the rpm version of Todo? (Even if you want to use the flatpak version)
For the sake of it, I’ve uninstalled the flatpack version and compiled the app from source.
It required a newer version of the GTK4 (4.9.1) than the one installed by dnf (4.8.2).

I had to build from source the new GTK 4.9.1! Meanwhile I opened a new bug, but it was a a temporary glitch. Finally I could compile and install the app with meson build, cd build, ninja and ninja install (a sequence nowhere documented in their repo)
After all, I have now /usr/local/bin/endeavour running fine.
