I need Enhance to work .

[Wildcat500]

I'm working in Win 11 with Photoshop 365 vs 24.4.1.  Enhance used to work, but in the last two "updates," it doesn't work - almost.  I just had an image come to me which was about 0.3 mb.  I thought that I would try Enhance and get it to not go as much pixelated.  It did it - in about an hour!  Now, the enhanced version is about 1.1 mb.  Okay.  The picture isn't quite as pixelated.  But one hour?!?  I just don't know about getting an image that is 60 mb enhanced so I can get a large mural out of it.  Can somebody help me know how to do Enhance?

We need to know more about your system (specifically the GPU). 

Review your system's specs and compare them to the minimum requirements document*: https://helpx.adobe.com/lightroom-classic/system-requirements.html

I have Intel UHD GPU. As far as I can tell, it should be supported.
