Unable to launch any Minecraft version with no errors or exitcode in the console.

Description of bug

I have used this launcher for a while on my other PC. But when i tried to use it on my laptop I was unable to start any version of Minecraft without any feedback in the console. I have tested it and it failed on Minecraft <=1.0, 1.16. and 1.20.. Log for Minecraft 1.0:

UltimMC version: 0.7.0-custom

Looking at the log I can see some odd details like the main class and params fields not being specified in the log:

Main Class:

Params:

The log also seemingly provided no exitcode or error message and just abruptly ends (yes it wasn't me to paste the full log in). This might be one of the harder to reproduce/unique to device issues, if that's so, can anybody suggest a fix for this issue?

Steps to reproduce

For me, with Microsoft Windows 7 x64, Java 17, UltimMC version 0.7.0-custom:

Create a vanilla Minecraft instance of any version.
Launch it.

Suspected cause

Possibly a fail to figure out/store launch parameters like the main MC class and start params.

This issue is unique
