Only 1 extension is enabled for capturing but still am able see \"error\": \"already running\"

I am able to see “Already running” text in Error field. What it means.?

“Video Capture Callback Status : {\n “success”: true,\n “status”: “success”,\n “error”: “already running”,\n “description”: “”,\n “metadata”: “”,\n “mediaFolder”: “C:/Users/spartan/Videos/Overwolf\\Remag\\CSGO\\CSGO_12-23-2020_17-30-37-101”,\n “osVersion”: “10.0.18362.1110”,\n “osBuild”: “1909”\n}”

Only my extension is capturing the video. here is the screenshot for the reference.

Can you please tell me the exact steps to reprduce? including the OW versin,which apps to install, and the code that you are using to capture.
