Hi @shaashwat - Thanks for submitting your bug report. We need a few more details to try to help with the issue.
Please see, How do I write a bug report?
What gpu driver are you using? Adobe recommends using the "Studio" driver version when working in Premiere Pro.
Do you have any third party panels, or plugins you are using?
Can you check your audio hardware settings and make sure Default Input is set to "No Input"
Sorry for the frustration.
