Desktop shortcuts cause Segmentation Fault

[doinkythederp]

Operating System

macOS, Linux

Version of Prism Launcher

Prism Launcher 7.1

Version of Qt

Qt 6.5.0

Description of bug

Desktop shortcuts of Minecraft Instances do not successfully start the game. Instead, they open a terminal window showing a segmentation fault error message.

Steps to reproduce

1. Click "Add Instance", select "Vanilla", and click "OK"
2. Click "Create Shortcut"
3. Close Prism Launcher
4. Double-click the file created on the desktop

Suspected cause

It seems related to downloading assets. This also seems specific to the --launch command line flag and doesn't happen when using the app manually.

This issue is unique

• I have searched the issue tracker and did not find an issue describing my bug.

I also have the same issue on KDE Desktop (KDE Neon 5.27)

The problem occurs both on CLI, and .desktop links, but launching the instance through Prism Launcher (no links, no arguments) works as expected

Steps and suspected cause is same as this issue.

OS: KDE Neon 5.27
Prism Launcher Version: 7.1
Command: ./prismlauncher --launch 1.20.1

i can reproduce

I can reproduce on Windows.

I don't know how to view the launcher console though.

I also just found out if you have a currently open Prism Launcher window, and use the shortcut (or thru cli), it [correctly] launches the desired Minecraft instance.

Another user on dicord provided macos logs of the segfualt and I was able to determine a possible cause
