Expected Behavior

The file dialog should successfully open without crashing the program

Current Behavior

OBS crashes with a segfault in libcef.so when a browser source tries to open a file dialog.

Steps to Reproduce

1. Open OBS
2. Add a new "Browser" source to the scene
3. Change the link to a page containing a file dialog interaction (i.e.: https://obsproject.com/tools/analyzer#logFile)
4. Right click on the source and click Interact
5. Trigger the file dialog on the website
6. Observe the crash

Anything else we should know?

Here is a link to the related discussion in the OBS Community Discord server.

Here is the gdb output: (except the libcef shipped doesn't have debug symbols so this is probably not the most useful)

This issue has been reproduced by a friend on Linux Mint Cinnamon 21.1 with the same OBS version

I have attempted to use both the Flatpak, the prebuilt binary from the PPA and building the program from source code, all of these lead to the same crash. The version in my distro's repos (https://packages.ubuntu.com/kinetic/video/obs-studio) does not contain the obs-browser plugin therefore, the crash is not reproducible there

I can reproduce this crash on the OBS 29.0 Beta 2 version aswell.

I cannot replicate this, on both x11 and wayland it appears file selection is disabled.

Also looks like its already tracked in the correct place over at obsproject/obs-browser#384
