Cannot launch AppImage from terminal

[jaredmcateer]

Bug Report

Summary of Current behaviour

Launching the app from the terminal results in infinite exceptions being thrown from the UI. Double clicking the AppImage executable from a file explorer or desktop work as expected.

Steps to reproduce

Run the AppImage executable from the terminal:

./NexusMods.App.X86_64.AppImage

Note

While writing this issue I saw that in the .desktop file that %u is supplied as a flag for the execution and running ./NexusMods.App.X86_64.AppImage %u does indeed work, but it is not intuitive. Also the log to the console claims Unrecognized command or argument '%u'. so I think this might just be a happy accident.

What is the expected behaviour?

Running the app from the terminal should run the same as running it from the desktop

Other information

First this:

Then this forever:

There is more information if I enable logging to console when I run it from the terminal:

nexusmods.log

Kinda curious what's going on here, or even how's going on here.
In theory it should execute the same, terminal or not, unless the bash profile, etc. have some overrides.

It seems the current working directory can't be fetched, but I wonder why, and how.
I'd need to dig into the internals here.
