The screen won’t turn on after updating the phone from Android 13 to 14

Dear 8849 Phone Team. The screen won’t turn on after updating the phone from Android 13 to 14.Two days after being updated, a system notice tells me that there is a new update of the device, but when I try to install it, it tells me, that the package could not be uncompressed, a few days later the screen was completely dark. I already restarted the phone, but it is still completely dark.

Thank you
