Hi. I'm David, and I'm happy to help you.
Error 0xc0000020 usually points to corrupted system files or drivers. Checking how Device Manager is detecting the camera is the best first step.
Please check the camera's Device Status:
- Press "Windows + X" and select "Device Manager";
- Click on the "View" menu and select "Show hidden devices";
- Expand "Cameras";
(If this category is not displayed, let me know.)
- If the camera is listed, right-click and select "Properties". Check if there is an error in "Device Status".
If you prefer, share a screenshot. Use the shortcut "Windows + Shift + S" to use the screenshot tool.
Also, share a screenshot of your system information.
- Press "Windows + R", type
msinfo32and press Enter.
Maximize the window and use the screenshot tool.
Looking forward to your reply.
