OBS fails to start properly when "Replay Source" filter is active in a scene

[jfchadeyron]

Describe the bug

When the "Replay Source" filter is added to a source in any scene, OBS no longer starts properly. The process is launched, but no graphical interface appears — it seems to hang during startup.

To Reproduce

Steps to reproduce the behavior:

1. Add the "Replay Source" filter to any source in a scene.
2. Close OBS.
3. Try to start OBS again.
4. OBS process starts (visible in Task Manager), but the interface never shows up.

Expected behavior

OBS should launch normally even if the "Replay Source" filter is active in a scene.

System Information

• OS: Windows 11
• OBS version : 30.x and 31.0.x
• Replay Source plugin version: 1.8.1

Additional context

If I remove the plugin or manually delete the filter from the scene config file, OBS starts correctly again. This issue seems directly related to the presence of the Replay Source filter at launch time.

Same issue if add the "Replay Source" filter to any web source.

Trying to replicate the issue, but all seems to be working fine for me. Can you provide an OBS log file of a session with the issue? You can find them in the OBS Help menu or manually in %APPDATA%\obs-studio\logs
