Re: Canon R5 help...weird swirls in images

Hi,
I have a Canon R5, and during editing, especially when anything over a +8 bump in shadows or small bump up in exposure is done this weird circles pattern engulfs the image making it unusable. I've exaggerated the edit it in the attached image so you can see the pattern, but this doesn't happen on my 5D IV or 5D III when doing the same thing with the same settings. It's pretty much rendered the R5 useless because it shows up doing very minimal editing using Lightroom or ACR. It shows up at most ISOs, and the images across all ranges seem noisy (no matter of how much light I get on the sensor. Is it a noisy camera compared to the 5D IV, even just raising shadows a little seems to bring up noise the 5D IV doesn't have issues with pulling up in the same settings/setup. I can't reproduce the patterns/swirls doing the same on my 5D bodies.
Can anyone help? Is my R5 faulty?

Any help would be great, I'm totally stuck.
Thanks.

I've been on the phone for an hour with Canon and then the rest of the afternoon with Adobe. The swirls are not there if the photos are opened in Canon's Digital Photo Professional 4 or in PhotoShop. You can edit the photos there and then export them to Lightroom Classic so that you can have them in your Lightroom Catalog. The moire effect is only visible in the Develop Module of Lightroom Classic, not in its Library Module. Adobe is going to try to figure out what is going on with CR3 photos shot at high ISOs and then call me back.
By the way, Canon said that the electronic shutter is fine to use for high ISO images. Using the manual shutter in an R3 should not be necessary to stop the moire effect showing up in the Lightroom Classic Develop Module.
One problem with using DPP4 is that it takes forever to load and then process edits on Apple computers using the new Ventura 13.2.1 MacOS.
