Flatpak: runtime org.gnome.Platform branch 46 is end-of-life,

Hello
I’m using Ubuntu 24.04 LTS. Lutris is installed as a flatpak, and since April 18, I’ve been getting this message:

“Info: runtime org.gnome.Platform branch 46 is end-of-life, with reason:
The GNOME 46 runtime is no longer supported as of April 17, 2025. Please ask your application developer to migrate to a supported platform.
Info: applications using this runtime:
net.lutris.Lutris”

It’s impossible to launch a game, such as Diablo, with Battle.net. How can I resolve this problem?

Thank you.
