Crash when deselecting mods after searching for another mod

[DarkIceXD]

Operating System

tested on Linux and Windows

Version of Prism Launcher

Prism Launcher 7.1

Version of Qt

Qt 5.15.9

Description of bug

When deselecting mods, after a search, in the "Download mods" menu, the launcher crashes completely.

Steps to reproduce

• create a new instance with Fabric or Forge, etc.
• edit the instance
• go to "Mods"
• press "Download mods"
• select any mod
• press "Select mod for download"
• enter anything into the search field so that the mod disappears
• press "Deselect mod for download"
• crash

Suspected cause

Very likely using a reference to the mod entry inside the GUI that got removed after searching. (use-after-free)

This issue is unique

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

I have the same issue, Flatpak PrismLauncher 7.1
It was very annoying ._.

This isn't a new bug either. It was present in earlier versions too. I also forgot to add that the same thing happens when selecting mods so:

• create a new instance with Fabric or Forge, etc.
• edit the instance
• go to "Mods"
• press "Download mods"
• select any mod but don't press the "Select mod for download" button
• enter anything into the search field so that the mod disappears
• press "Select mod for download"
• crash
