Start with this check.
Confirm the meeting website address and review its Chrome camera permission. Then select the device that worked in Windows inside the meeting.
Allow camera access only on a website you recognise. Keep private documents and people who do not want to appear out of the frame. Do not grant access in response to an advertisement.

Let’s go step by step.

Establish a valid comparison
Open Windows Camera, identify the device that produces a picture and close the app afterwards. Open the official meeting address. Record whether Chrome detects no camera, shows black or reports denied access.
Do not compare the built-in webcam in one test with a different USB camera in another.
Review the website permission
In Chrome, open Settings → Privacy and security → Site settings → Camera. Find the meeting domain in the exceptions and change its access if you previously blocked it and now want to use it.
Reload after the change. If permission is requested again, verify the domain before accepting.
Check the system control
In Windows, review Settings → Privacy & security → Camera and desktop app access. A working store app does not replace this browser access check.
If the control is managed, keep the message for the administrator rather than changing policies to bypass it.
Choose the input inside the meeting
In the meeting preview, review the camera selector and video button. Choose the device identified at the start. Avoid a virtual camera unless that is the input you actually intend to use.
If the preview returns, confirm it comes from the correct camera before joining.
Restart the test session
Close other calls and tabs using video. Save forms before restarting Chrome if the change does not apply. Compare the same site afterwards; another trusted meeting service’s preview may help isolate a service-specific failure.
If only one site fails, report its domain, version and message. Avoid deleting all browser data as a first response.
When to stop and ask for help
A work policy needs administrator support. If Windows Camera starts failing too, return to device troubleshooting. If only one service fails, use its help with your comparison results.
Does a step differ from what you see? →Common questions
Must I allow every site?
No. Review the particular domain you need.
Does this path apply to Safari or a phone?
Not necessarily. It describes desktop Chrome on Windows 11.
Why is the preview black with permission granted?
Permission is one condition. Selected camera, video controls and other applications still need checking.
