Recovering lost version of photoshop

I have been very cautious about updating Photoshop on my Windows 11 PC. I kept version 2023 with all of my plugins installed. Some of which had to be modified based on instructions I got from the original plugin developer because they aren't available any more. I couldn't afford to lose them, so I never updated that version, nor did I update 2024. I did install as a new application, the beta and I have been keeping it up to date.

Today, for the first time, I look at the creative cloud app and it prompts me to install Photoshop. 

I went to my Start Menu and sure enough only the Beta is installed.

I go to my Program Files folder and the Photoshop 2023 folder is empty as is the 2024 folder.

How could this possibly have happened and what can I do to restore these apps? 

Any help before I stroke out would be greatly appreciated. $70/month did not grant Adobe full rights to delete the software I am licensing from them and even if it is in the fine print, what kind of evil company would do that without warning or confirmation?
