Camera Disappeared from Blue Iris

[HomeWPOE]

BI v5.9.8.5. Had a camera disappear from BI a day or so ago (have 6 cameras total). The missing camera was also missing from the BI Status->Camera list. It was still present in the Windows registry (HKEY_LOCAL_MACHINE\SOFTWARE\Perspective Software\Blue Iris\Cameras\xxxx). No problems accessing the camera (EmpireTech/Dahua) directly via the browser GUI.

I added/reloaded the camera to BI using the same name. By using the same name was hoping I could still access the past few weeks of timeline videos and alert videos. Was able to achieve realtime functionality and recording capability, but no access to past videos or alerts.

Anyone have any idea what might have caused this camera to disappear/drop from BI like this?

Thanks.

I've never had that happen. Could it be an overactive anti virus "protecting" you ?
