Can't create new file in Photoshop CC 2020

[benm51845155]

Since updating from 2019 to 2020, I've seemingly lost the ability to create new files. I've been opening pre-existing files, deleting all the layers and resizing the canvas to create new files, but it's very annoying.

I have the same problem still after this time... using Photoshop 2020
