Expected Behavior

Browser sources should render both in the preview window and in the properties tab, and this behavior should be retained through reboot.

Current Behavior

Upon reboot, browser sources are still present in the sources list, but do not render. This is because CEF fails to initialize.

Steps to Reproduce

1. Install and launch OBS Studio 32.0.4.
2. Create a browser source, then close OBS and restart your system.
3. Launch OBS. CEF should now fail to initialize, causing the browser source not to render.

Anything else we should know?

Once 32.0.4 has been installed, browser sources appear to permanently break even when rolling back to older updates. OBS must be fully uninstalled and 32.0.2 must be installed in order to prevent the issue.

My best guess is that this has something to do with the changes to shutdown logic in 32.0.3, but this is speculative.

Start by reviewing the linked OBS log and reproducing the browser-source failure on OpenSUSE after a reboot with OBS 32.0.4. Trace where CEF initialization is handled during startup and shutdown; done means browser sources render in both the preview and properties tab after reboot, without breaking after rollback.
