Backup actions, presets etc. Also, consider using the cleaner software:

what would be the implications for my existing payment contract?

Uninstalling does not release you from your contract — there is a fee for early cancellation.

• Was this working before and just started? If so, did you do anything new about the time it started?
• Have you tried resetting preferences?

  (Backup customization first)
• Did you just start a subscription (you have 14 days to cancel a new subscription)
• Does an earlier version of Photoshop work on your current system?

How did you get on Wayne?  Have you reinstalled, and if yes is Photoshop working?

We can see you are using a Windows system.  If you are still having trouble, can you describe your system for us?  Thanks.

No problem, just reinstall.
