Failing to launch compiled apps

[Elizabeth Muro]

Hello, I have a web app which I use Web2Exe to convert to an exe. It appears to launch just fine for most on Win x64, but fails to launch when users try to open it via Proton, Proton GE, Proton Experimental, or Desktop mode on the Steam deck. 

A debug.log file can be found in the game's root folder with this:

What could be going on, and is there some sort of fix I can implement?
