Multi GPU = no transform tool ???

Hi,
Following the release of version 24.0 of Photoshop, I no longer had access to the basic "Transform Tool" and, unable to find a solution, I ended up formatting my computer...

So, I have a brand new system, up-to-date drivers, and an up-to-date version of Photoshop, yet the same problem persists (and you can appreciate the joke of  "click to discover how to fix the problem" that sends you to a 404 page) !!!

Eventually, I found a workaround: I disabled graphics acceleration in Photoshop options, even though the included GPU testing tool indicates that my graphics cards are compatible.

But I have TWO identicals graphics cards, so what ?

- Does Photoshop have a bug when there are more than one graphics cards in 2023 ?
- Is this normal or just me ?
- Is there a way to force Photoshop to only use one of the graphics cards (which would be better than none) ?

I am dismayed to see the implementation of "Neural Filters" that require GPU... BUT THE CORE OF PHOTOSHOP DOESN'T SUPPORT MULTI-GPU???

Thanks in advance, I am at my wit's end. And sorry for the capital letters, I had some frustration to vent after all the time wasted reformatting my system for nothing...
