Front camere doesn't work

Hi,

After I update IOS 15.4 the front camera on my Iphone 13 Pro Max stoped. I reset all setings, restart my phone several times, change camera between front and back camera, but front camera can't open - steel black screen. It doesn't work in other apps such as FaceTime, Viber, WhatsApp and others.

Can you help me?

Best regards,

Kristiyan Ivanov!
