Microphone not working on third-party apps

Iam using an iPhone 8 and the microphone of the phone is not working on any of the third-party apps such as snapchat, telegram, whatsapp, facebook messenger, etc. also the voice memo is not recording any of my voice it's just picking up some minor static sound. However, the microphone of the phone is working fine with the iMessage voice note, front, back camera while recording a video.

The phone's microphone was working fine till the evening when this issue encountered out of nowhere. I have already updated my phone to the latest iOS 14.5.1

Also, i have performed a hard-reset, resetting all the settings and yes, the microphone's privacy is not restricting any of the third-party apps.
