Photoshop gone after an computer update

[Elaras love]

I bought photoshop a few years ago and yesterday I switched from Windows 11 back to windows 10 because I had some computer issues. Doing so swiped my computer clean. I was placing everything back on it today and I can't get photoshop back without paying for it. What can I do?
