Hello Freedom The Taube's.
Welcome to Microsoft Community.
Regarding to your information I assume that you can't use your microphone because of the Microphone permission error.
Based on your description, it seems that you are facing a permission issue. This could be caused by a corrupted account configuration file.
Therefore, I suggest you try the following steps and let us know the results:
Please create a new test account, and switch to the newly created account to see if the Microphone is working as normal.
This troubleshooting step can help isolate the problem due to an invalid profile configuration.
Create a local user or administrator account in Windows - Microsoft Support
If there is anything not clear, please do not hesitate to let me know.
Best Regards,
