If the OP was to save the edits to an xmp file, and then share that along with the RAW file, could we then see someting different? Perhaps see what the OP copy of LRC is doing?

Well, as this is a raw file, and opened in Win 10 photos app, I do get this:

But when opened in ACR in Photoshop (which is the same engine as in Lightroom Classic) I get this - opened in ACR in Photoshop - profile is set to Adobe Standard:

So, probably, it is something to do with your colour profiles, or, your monitor profile.

I don't see any abnormal colour issues.

I am using the monitor profile for my specific NEC calubrated monitor.The issue isn't just with "how it looks", any tweaks to the image rail the histogram to crazy levels in the red channel also.

The issue is even if you tweaked the saturation up to 20, the shirst and some of the roses go completely neon.

I'm not seeing any of this on my screen.

Please post a screenshot of the entire Lightroom window with the unedited image open in Develop.

Make sure that the History panel is visible and expanded on the left, and that the Histogram and Basic panels are visible and expanded on the right.

Naturally we have no idea what Profile you are applying. Default? Try a camera matching one.

Otherwise, the Orange does not scream out dayglow on my rig.

It's a Raw, man. You don't like Adobe default rendering, you have the power to change it. That's why you shot Raw, right? Ya' know, the personal touch.

Looks like a "normal" orange sweatshirt on my monitor as well. What monitor profile are you using?

I don't know what the sweatshirt is supposed to look like, but the general colors in the image look OK to me.
