Poco X2 — Camera issue

Address:

Ayisha Garden, Lakshmi Nagar, 3rd Street, Melamaiyur, Chengalpattu.

I've been facing issues of my back camera of Poco X2 as it got freezed and its showing only a black screen. But the selfie camera is working fine in some apps alone. Also heard this complaint by many other users over the last few months. Please fix my issue. Thanks in advance.
