CC2020: can't write document presets file error on close in Photoshop; can't relaunch after

[Sejjr33]

I have an issue which has only just started after updating to the latest version of CC 2020. When I close the program, I receive the "can't write document presets file" message. If I try relaunching Photoshop, either clicking the App or using the CC launcher, it will not open. I have trashed old preferences and am able to relaunch the program but only after a full system reboot. I am running an updated Windows 10 machine. Any suggestions on what to try next?

Check your User ID access to its Photoshop Preferences folder make sure it has full access rights.

Yup, I too have the same issue and have attempted all the suggestions none of which solved the problem. Whilst I can live with it it is somewhat annoying.
