Composition Panel is blank

Hi, there's a number of people reporting the same issue over the years and unfortunately in my case no fixes work permanently.

Tried the suggestions detailed here: https://community.adobe.com/t5/after-effects-discussions/blank-composition-panel-in-after-effects/m-p/12113006#M173458

This works for about a minute before failing again: https://www.youtube.com/watch?v=niPcTsM7SGU

Basically when I create a new comp, the composition panel is blank, but any elements in the space can be clicked on, they're just now showing on screen. If you hit space to play, it moves along one frame and stops. Deleting the After Effects folders in  C:\Users\me\Documents\Adobe and C:\Users\me\AppData\Roaming\Adobe work but literally for about a minute, then once the folders repopulate the composition panel freezes.

Anyone had any luck killing this thing permanently?

This is a fresh install of AE literally an hour ago, brand new laptop. It is a company machine running a virtual desktop so that could be an issue, but I seem to be able to fix the problem, albeit temporarily, so something's changing after a minute or so!
