My images appear pixelated in Photoshop 22.0.1 on Windows 10

Hi all,

I recently purchased adobe creative cloud with photoshop, lightroom classic etc. However when I open an image in photoshop they appear pixelated.  It doesn't matter whether they're jpg, raw or psd. However they seem fine in lightroom.

My computer is a few years old it but it's decent. It has 8gb of ram, 256gb ssd (which is only half used) and running windows  10 version 1909.

I've attached a screenshot of an image, you can seen the moon is clearly pixelated.

Has anyone come across this and got a solution?

Many thanks, Niall
