It seems to be some hardware failure.
If you have a warranty, why not to contact a Huawei customer service center nearby?

Restart the system. Screen freezing problems are at times fixed by simply refreshing the system. Make sure to restart the phone and see what happens. The Huawei P20 Pro has a non-removable battery pack so understandably, you will be unable to disconnect the battery to restart it. In order to achieve the same result though, you can just hold down the power button until the screen goes black. If the cause of the problem is a temporary bug, this reboot may help.

If the problem remains after this type of reboot, proceed to the next troubleshooting step.

Here’s what you need to do:
