Photoshop 2019 (20.0.9) Freezes whole computer - Windows 10

Hi, I recently bought a new PC that was quite expensive, mostly for using Photoshop, and unfortunetly I'm experiencing a bunch of issues using PS that I won't go into detail now except for the most severe one - Photoshop freezes and the computer freezes with it and becomes completely unresponsive. As in, the mouse and keyboard don't react at all and the only option I have is to hard reset it. I can't terminate any tasks as well because the keyboard stops working. I should probably also mention that if I'm listening to music when this happens, the sound stays on, although it becomes stuttery and robotic. One time the computer froze and all the colors seemed to revert from 32bit to 16bit, and then it automatically reset itself. The worst thing is that every time this happens I lose all the unsaved progress I made, although I try to save my progress every few minutes.

It sounds like I might have some faulty drivers or perhaps the hardware itself is defective, I honestly don't know what to do and the worst thing is that this computer is barely 2 months old. I'm using an older version of Photoshop because I didn't like some of the changes made in PS 2020. I don't know if this freezing happens when using the newest version. Is this a graphics card issue perhaps?

Some info I hope is relevant:

OS - Windows 10 Home - 10.0.18363

BIOS - American Megatrends Inc. 2606, 24/10/2019

Motherboard - Asus TUF Z390M - PRO GAMING

Graphics card - Nvidia GeForce RTX 2060 Super (updated with latest Nvidia drivers)

Processor - Intel Core i9 9900K, CPU @ 3.60GHz

Thank you very much for reading and for your help.
