woah nice, I'll try it right away to let you know if it works, although I probably won't be able to finish it because I'm finishing a job and the deadline is in like 12 hours
hey maybe I could help, could you send me a screenshot of your project settings? It's really weird because I've never had issues deploying to Linux with Godot.
Aside from the embed pck option everything seems to be like default. That's really weird. Are you using 3.3.3? Maybe you could try exporting it with an older version (it has happened to me that sometimes new versions break stuff in my games, even if they're small updates like 3.3.3)
