I have lost my photoshop - Launch Error: Missing dxcore.dll

Phtoshop updated on Tuesday and now I cannot open it. I keep getting a message about a missing Dxcore.dll. I have reinstalled and nothing. I spent 2 1/2 hours with Adobe. Their only answer is to update to Windows 11. It was working perfectly two days ago, and now-nothing. I am devastated. I have been a faithful adobe user since photoshop 4. I have spent a fortune and am currently a monthly subscriber.  All I wanted was a link to reinstall a previous version of 25, but no one can help me.  This is not right. There is nothing wrong with my operationg system. As I said, photoshop was working fine just two days ago.  Now it looks as if I am going to have to give up doing graphics.  I am so upset, I do not know what to do.
