Expected Behavior

Virtual camera should be activated if it wasn't already.

Current Behavior

Obs crashes in function TaskbarOverlaySetStatus() at line taskBtn->setOverlayIcon() because taskBtn is null.

Steps to Reproduce

1. Create plugin.
2. On OBS_FRONTEND_EVENT_SCENE_CHANGED event call obs_frontend_start_virtualcam()
3. Run obs

Anything else we should know?

I have made some modifications to obs so lines or address may be shifted. But nothing that could have impacted the camera.
If I "jump" over the first event trigger by adding a variable first_run (which is set after the first SCENE_CHANGED is triggered) then the call to obs_frontend_start_virtualcam() succeeds on all subsequent events.

Start with OBSBasic::OnActivate and TaskbarOverlaySetStatus(), then trace the OBS_FRONTEND_EVENT_SCENE_CHANGED path that calls obs_frontend_start_virtualcam(). Review the linked log and crash log to confirm the null taskBtn condition. Done means starting the virtual camera from the plugin event no longer crashes OBS when it is inactive.
