Adobe Photoshop freezes

Maybe somebody here has a solution for my problem. I'm even not able to work because the whole app freezes. What I noticed is very high power usage. Does somebody know why it happens? I think I have quite good computer and it shouldn't happen.

Below you can find my computer details:

DELL Precision 5530

16GB RAM

Intel Core i7-8850H

Graphic cards: NVIDIA Quadro P1000, Intel UHD Graphics 630
