Latest Dino from Flathub (0.4.3) just hangs while "beta" (0.4.2) version works fine

[Newbytee]

Using Dino 0.4.2 from Flathub running on a phone in Phosh, I'm able to use Dino normally. I was using Dino from Flathub Beta as when I first installed it, there was no Dino on Flathub (stable). However, since then, the beta branch stopped updating and now is just stuck at 0.4.2.

Today I realised that it was an outdated version and installed Dino from the stable branch which is at 0.4.3, and Dino just hangs on startup. No errors are printed if I run it from a terminal, just runs indefinitely with no GUI appearing. If I revert to the beta version, Dino runs like normal. I've not changed any permissions in Flatseal, and I also tried removing all the data from ~/.var/app/im.dino.Dino, but nothing changed.

System:

• Device: Purism Librem 5 (aarch64)
• OS: postmarketOS Edge
• Distribution method: Flatpak from Flathub
• DE: Phosh

I can reproduce the same issue on Linux Mint (Cinnamon).

Debug messages don't seem to contain anything useful (the are exactly the same as for 0.4.2, which does work):
