Photoshop and Illustrator use over 30GB of memory to launch (no files open)

[SonOfWill]

A couple introductory notes:

I'm on a 2017 iMac Pro with 3GHz 10-Core Intel Xeon W processor and 64GB Memory.

I've worked with two Adobe support members and they couldn't figure out why this was happening. Apple support hasn't either - though we are still working on it. But I figured I'd try to see what the community thinks!

Long and short, any time I open either Photoshop or Illustrator (other apps like premiere or Lightroom don't appear to do this, they eat up over 30GB of memory just to launch - no files open. We've tried a number of things:

- uninstalling/reinstalling

- They are uptodate

- Clearning caches,

- Disk Utility and IOS resets

- and a few other thigns

We have discovered that, making a new apple user account and testing it there, the problem doesn't happen. I can open either application and they sit around 400MB at launch, so the issue seems isolated to my user account in some form. 

I am a graphic designer by trade, and relatively saavy with tech, I'm hoping anyone has any ideas why this would be happening? Any help would be tremendously appreciated.

Thanks!

I was having this same issue, Photoshop & Illustrator each using up around 30GB each at launch, unable to use both at the same time, crashing midway through projects. Ended up solving the issue by unistalling each Adobe program one-by-one, then uninstalling Creative Cloud. After re-installing everything, seems like it all is working normally again under 1GB each at startup. I also updated all outdate programs on my machine & had to unplug my external monitor/tablet when not in use.
