Hi sophiashu,
Thank you for reaching out Microsoft Community. We're sorry for the inconvenience this has caused you.
Since this only happens on Google Meet, what I'd like you to do is to contact the application developer to check if there's anything to be configured on this program or you can check with them if this is commonly happening to Windows devices not only limited to Surface.
For issues happening in third party applications, what we can suggest is to uninstall/reinstall the app and if the problem persists, it's be to have this addressed by the application developer.
Kind Regards,
Crest
