Camera, YouTube, and some apps downloaded from the Playstore are not working

[Wellington123]

Good morning people. All right? After the penultimate update to MIUI 11.0.2.0 stable - I'm already on MIUI 11.0.3.0 stable - my Xiaomi Redmi Note 6 Pro has been having some problems. I am not able to use the camera, YouTube and some apps that were downloaded from the Playstore. Every time I click on the icons of these apps, the device crashes. Apps like WhatsApp, Instagram, Messenger and others are also not running the camera inside them . I ask for your help in solving this problem. I'll be very grateful!
