Signal desktop suddenly crashes on Ubuntu 24.04.1 Wayland

[greguti]

Was using Signal Desktop flawlessly for more than a year on my Ubuntu laptop (Asus Zenbook 13 OLED).
Since yesterday, refuses to start.
Installed with FlatPak.

Here is the terminal output when trying to launch Signal.
After a while, sometimes a popup opens asking if I want to delete all my data to launch a new Signal, and then a warning that all my data will be lost.
When I click Yes, a new Signal Deskop launches, I can pair it with my smartphone and it works ok... But then, if I close Signal Desktop and I try to launch it again, same error occurs.

flatpak run org.signal.Signal

This issue seems to be the same as #723
