OBS closes with no error reports in log when I click ANY button that browses files.

STEPS TO REPRODUCE

2. 
3. 

OBSERVED RESULT

When I click a browse button anywhere, OBS closes with no useful report in the logs.

EXPECTED RESULT

When I click a browse button (...) like inside "Remux Recordings" or the filepath for a media source it should open a dialog to browse files.

KDE Plasma Version: 6.0.4
KDE Frameworks Version: 6.2.0

ADDITIONAL INFORMATION

The issue happens wether we use the distro's repo version or Flatpak, the issue has been reported here: (https://github.com/obsproject/obs-studio/issues/10683) and it's been stated it should be reported here.
Friend also encounters the issue on Arch | Plasma 6.0.4 

downgrading kwidgetsaddons seems to fix the issue.
Comment 1 Christoph Feck 2024-05-19 23:46:08 UTC 
Nate, did ef1ea307 land in a released version, or did Arch package a pre-release?
Comment 2 Christoph Feck 2024-05-19 23:48:18 UTC 
Could also be related to bffd3b79. It is a recursion, after all. Maybe OBS uses setPalette().
Comment 3 Nate Graham 2024-05-21 16:53:28 UTC 
I can confirm that ef1ea307 did NOT land in 6.2.

You're right that bffd3b79 also looks relevant. I can confirm the reported issue, and if I revert bffd3b79 locally, the issue goes away. so yeah, looks like bffd3b79caused it.

Joshua, can you take a look?

KMessageWidget: Avoid calling polish() inside of palette update

This causes infinite recursion as the palette is set and unset when the
application uses CSS stylesheets. But this call is simply unnecessary
and can be removed.
