[marblokfromminecraft]

Please confirm the following.

• I checked the existing issues for duplicate problems
• I have tried resolving the issue using the support portal
• I have ensured my Modrinth App installation is up to date

What version of the Modrinth App are you using?

0.14.6

What operating systems are you seeing the problem on?

Linux

Describe the bug

ModrinthApp crashes on Linux. I use Debian 13 testing, but this is also an issue on other distributions.
A part of this issue was already reported in #6382
In steps to reproduce, all crash reasons are listed.
Please fix this. It massively downgrades the experience on Linux.

Steps to reproduce

1. when you view an instance linked to a modpack
2. when your mouse is over the +1, +2, ... by the tags in the browse content tab
3. when you click on the 3 dots by a word in the jump back in section on the home screen
4. When you click the 3 dots by a world in the worlds tab in an instance.
5. when you click the downwards arrow next to the + button or the + button in the files tab of an instance
   And probably more things that I can't find...

Expected behavior

That the app just performs the action and does not crash.

Additional context

Debian 13 testing, updated and installed via Flatpak, but this is also an issue with the .deb, .appimage, ... and on other distributions.
