Xiaomi Mi 11 Lite Front Camera Not Working

Hi there, I'm having trouble with my Xiaomi Mi 11 Lite's front camera not opening. I believe it may be a software problem since the rear camera is functioning properly. Whenever I try to switch to the front camera, it refuses to open and doesn't allow me to switch back to the rear camera either. Through my investigation, it has come to my attention that this problem is ongoing and has impacted numerous individuals who own Xiaomi devices, including myself. In the past, a number of Xiaomi phone users encountered a common problem with their power buttons. In the past, I had the button replaced while it was still covered by warranty. However, now that the warranty has expired, I find myself uncertain about the next course of action.
