What s wrong with my cellphone screen

I do not know if you can see it but on my screen all the time I see such a small section of Youtube and it just annoying. But it is only since today and I wonder what's going on. Even the keyboard hangs after even though my phone is only 2 months old.

Important Info: Huawei Mate 10 Lite

Android 8

64GB memory +24 GB memory card

Please help me I want that stupid Youtube background goes away.

Time Task Manager opened and YouTube quit? At Huawei, you probably open it by clicking on the square.
