Can you try to follow the steps documented [here]https://docs.flatpak.org/en/latest/debugging.html#running-debugging-tools) to run Moonlight under gdb and then run bt when it crashes?

I cannot find Debug symbols in flatpak repo, thinking it should be builded manual. Possible strace may be helpful com.moonlight_stream.Moonlight.txt

Today i setup fresh installation of Mint Mate. Before updates i check moonlight flatpak - it was working (say no drivers for decoding, but it run). After, i setup updates and NVIDIA driver. As result - same error, flatpak not working. Rever driver to opensource - moonlight run again.

[cgutman]

Hmm, seems like a Flatpak runtime issue with the NVIDIA driver. There are quite a few hits for "stack smashing detected" related to the Nvidia driver on Google.

Can you run flatpak update, then flatpak install com.moonlight_stream.Moonlight.Debug and try to get another backtrace?

I'm getting the same issues, i'm not using an nvidia card (if that's related?, I'm using Ryzen 5500u iGPU, Linux Mint), and I didn't know how to debug it properly as i'm getting the error "runtime/org.kde.Sdk/x86_64/5.15-23.08 not installed" (Along with a very similar report as the OP, can't install 'libxapp-1'). I don't know how to fix this, 'flatpak repair' as I've found on internet didnt work.

If anyone stumbles upon this, the Flatpak was broken for me too, today suddenly it didn't work anymore The temporal workaround is downloading the latest AppImage from Moonlight, making it executable with 'chmod +x' and executing it.
