@ThisNameIsGoudaNuffC hello, please try to solve the problem by resetting the accessibility settings. Go to Settings/General management/Reset/Reset accessibility settings.
If the problem persists, reset the app preferences: go to Settings/Applications-the three dots on the top right-Reset preferences. I hope these steps help you solve the problem.
@ThisNameIsGoudaNuffC In this case, try this: access the Safe Mode of your phone. Activate your mobile data, since by default Safe Mode starts in Airplane Mode. You must have the Meet and Duo apps available. Make video calls, to verify if the The problem persists. In case the error is not present in Safe Mode, you must have a third-party app that causes the error.
If the error persists also in Safe Mode, I personally would Reset all settings and as a last resort -Reset to factory values.
