A clear and concise description of what the bug is.

I tried playing the recently released "Doom 64: Unseen Evil" mod, which basically converts all the Doom and Doom II assets to play and behave like Doom 64, and I am getting a consistent crash whenever I tried to load any level of any game/episode.

I remember I tried running this a while ago (before October 15th), and I was able to get it to run into the first level (E1M1) with the D64 assets, however, I didn't continue playing since I was modifying some controls options and left it there for the weekend. It wasn't until yesterday that I came back to it, and to my surprise, now I couldn't get it to run anymore.

I'm running GZDoom on a Steam Deck, with the Flatpak installed being up to date.
I ran the Flatpak through terminal with flatpak run org.zdoom.GZDoom, and at the very end I got the crash log, here's what I got:
(SEE LOG REPORT BELOW)

Running the standalone EXE through Wine makes it work properly, and if I extract the Linux executable from within the .DEB file I can also run it with no issues. The problem arises when attempting to run it through the Flatpak release.

However, I tried bringing this issue up to the people in charge of the Flatpak of ZDoom for Linux distributions by issuing an issue report on their GitHub, but it seems like the issue may be rooted in GZDoom itself rather than just the Flatpak:
flathub/org.zdoom.GZDoom#78

To quote Eonfge:

Then it's likely related to this:
#2656

Long story short, GZDoom plays fast-and-loose with some compiler-checks while the Flatpak app demands certain checks for security and reliability.

The log I posted seems to hint at the possibility of the issue residing in some of the compiler checks when running the game, since the game does boot with the mod, but it only crashes when I attempt to play any level whatsoever.

Steps to reproduce the behaviour.

Explain how to reproduce

1. Get a copy of Doom/Doom II
2. Download "Doom 64: Unseen Evil" and configure GZDoom to launch it
3. The game crashes as soon as selecting any level from any episode

Your configuration

Fresh install on every instance of running GZDoom, no config changes made.
