Canon EF lens correction data shifting color profile

Hi, I'm having a color managment issue with my Canon R5 & RF 24-70 lens. My editor/post processer of 7 years sends me jpegs that look washed out, missing reds, flat, etc. Everything looks good on her end and on my graphic designers end, so I figured it was my screeen (althougth all of us are on calibrated imacs, using the same color profiles, etc and same version of photoshop and bridge).For the first time in 20 years, I've gotten some complaints and comments from clients regarding the color. I recently started printing orders for clients and the prints match what I'm seeing on my screen (washed out colors, little to no reds, flat, etc) . Adobe escalated my case and said a senior tech would call me muliple times and never called. I finally spoke to Canon yesterday and they told me about an issue they are seeing some R5 or RF lens users involving adobe. I'm not techinical, so here's what I heard them say:

"Lens correction data is shifting color profile" and they recommend remoing the lens profle from Photoshop or adjusting defringing.

 

Any help would be appreciated. Thank you.

What do you think the issue is...why is there missing color?

Because, what Canon told you about the lens profile is rubbish. That has no role in this 'color shift'.

Here is a side by side right now of the same raw file in Digital Photo Pro 4 (left) and Adobe Bridge (right). The photo on the right is missing color...look at her skin and lips.

In Lightroom Classic you can select and disable in mass. In ACR, you'll want to do this one by one (although in theory, you can 'open' multiple raws there and do so). 

Do one! Does this change the color????

Can I turn it off for all of the photos and past photos ....or does it have to be done one by one?

You don't need to remove anything. You can toggle the profile OFF.

This is not relevant. How do I remove a lens profile in Camera Raw?

First, what she sees and you see is at this point going to have to be tabled. 

You should always test output using good color reference images designed for that task. The color reference images RGB values are such they are set for output and are editing and display agnostic. Test the output this way and examine for the same color issues so we know it's not your image specific issues causing the problems:

You can use this to print of course. 

Next, it might be useful to save off a DNG (it bakes in ALL your edits and profiles) and upload to something like Dropbox for us to examine. 

With an embedded profile and or course, a well calibrated and profiled display, what Photoshop shows you IS correct. Outside of a color managed application (which your editor may be using), not the case. 

Canon and Adobe (and ALL other raw processors) are proprietary and unique! It isn't at all unusual even with default settings that the same raw will appear differently in different converters. After all, this is really what your raws look like:
