My Xiaomi Mi 11 Life Mic & Camera Issues

I have a Xiaomi Mi 11 Life phone. There seems to be an issue with the microphone as the other party is unable to hear me unless I use headphones. The front camera is experiencing some issues, while the rear camera is functioning properly. Out of nowhere, all of these problems arose. This matter requires immediate attention. If someone has the knowledge to resolve the issue, I would greatly appreciate their assistance. I've watched so many YouTube videos, but it's been useless.
