Clicking any dropdown causes segfault

[justsomeon123]

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?

0.10.21

What operating systems are you seeing the problem on?

Linux

Describe the bug

Clicking on any dropdown, i.e. the menu that leads to "Add from file", leads to the app freezing for a second, then crashing.

Steps to reproduce

1. Click on hamburger menu next to a "jump back in" profile.
2. Watch app crash after freezing.

Expected behavior

1. Dropdown opens and doesn't freeze the app.

Additional context

System: Kubuntu 25.10, kernel 6.17.0
dmesg returns:

I get the same thing even just clicking on the logs! I ran modrinth-app in terminal to try and catch anything and got the following:
/usr/bin/modrinth-app: line 8: 251270 Segmentation fault (core dumped) env MODRINTH_EXTERNAL_UPDATE_PROVIDER=1 /opt/modrinth-app/modrinth-app "$@"

Running the latest version of Modrinth App via Arch User Repository, the game does run tho so its just an annoyance with log tracking for me

[TheoKritzinger]

I have this issue too.

[Radpc]

I also have this issue. It happens 100% of the time when I click on the dropdown near the Play and config buttons, on the instance details page.

Same issue here, Arch Linux 6.17.9

~~After experimenting for a bit, it seems like the environment variables "WEBKIT_DISABLE_SANDBOX_THIS_IS_DANGEROUS=1 WEBKIT_DISABLE_DMABUF_RENDERER=1 GDK_BACKEND=x11 GSK_RENDERER=gl" fix the issue, although I don't know how safe or secure this fix is. Definitely an issue with NVIDIA and webkit causing this, so I don't think that any changes can be made to the modrinth codebase to fix the issue. ~~

edit: the command sometimes allows for it to show dropdowns, but still crashes often.

[bigseabite]

I have the same issue on Linux Mint Cinnamon 6.4.8

Do we need to report this to webkit? I'm not familiar enough with webkit to know what information to send them.

[Jab11n]

Same issue here, Xubuntu 25.10.

[TotoShampoin]

Same issue here, Archlinux + KDE Plasma

[BeepSterr]

Affected by this too. Arch + XFCE
