Please report back after using the new batteries instead and see if you have similar results.
Also, which cards are you using (type, brand, and size)?

Why in god's name would buy a brand new expensive camera and not use the new battery that came with it. I don't get it. i know you have to wait for the new one to charge up so this whole story sounds crazy.

I don't have a grip so the battery was inside my camera getting hot. Did you have your viewfinder on high refresh? I did and it looked amazing.

I was to get the camera and be on a shoot and got delayed 2 hours. To be on location after the dam starts up is no good. So drove there an hour not worried about the new battery because I have 15 others fully charged that I believed were fully backwards compatible.
I have been using my 6D battery LP-E6 whilst the new ones are charging. The R5 tells me is in poor condition. I have been chimping, shooting hi frame rates, messing with IS lenses etc and the camera is barely warm and feels quite normal for a mirrorless camera. As soon as the new batteries are charged I will head out with the camera and will also try and report back.
Had an odd thought. Is there any chance you camera was in the back of a hot FedEx truck, etc., and warmed past 104 degrees, the operating temp listed for that camera. It's been 102 degrees here lately, and lots warmer in parked cars, or vans like my blue Transit when just sitting. Anyway, just wondered if there's a chance the package was shipped in warm enough conditions to need a while to drop to operational temperature.
Or, say, maybe sitting in a warm car for a while before coming home.

This is possible, but pretty unlikely. If Canon is using an entirely new chemistry with graphene or something I suppose it's possible.
Both of these batteries are lithium ion, both have the same voltage rating, and the E6NH only offers an additional 14% capacity.
Heat generated in the battery is a function of internal resistance within the battery (R) times the current leaving the battery squared (I) or I*I*R. In this case, with the two batteries you would see current held constant, so the only difference will end up being the internal resistance.
Given their similar chemistry, and apparently similar physical construction, it is extremely unlikely that the internal resistance was reduced enough to make that big of a difference in heat generation.
I'll be interested in seeing your future test results to learn more.

Don't let the people blinded by brand loyalty get you down. I find your experience extremely useful and can't wait to hear more!

Could it have been the 90D battery? When it comes to electric power tools it is bad for them to have less current than they require. I'm not an electrical engineer so this is just a crazy out of the box thought. While the battery is compatible perhaps just for short usage as a fill in?

I was out in hot weather but saw no one elses camera shut down. This was not the video warning but a separate battery warning.

I guess I should also clarify that it is actually possible you have a bum 90D battery here, where it has started to break down and the internal resistance is extremely high.
I was pretty sure the 90D battery was compatible.I looked it up and was about to post this with a screen shot. Battery condition can make a difference which is why I asked. I guess the test is with the one that came with the camera. Claude got a lot of shots in his post.

May be the first thing to check.
The 90D battery is one of three that I quoted in my post above, from Canon USA's R5 page. The specs section denotes that all three should work. Unless, like you say, it's a dud.
I hope this is an isolated situation and won’t happen again, but obviously you observed something that’s not expected. I’m going to follow this thread to see if you encounter the problem again. It sucks to have a brand new camera disappoint like this.

That's fine. I think people should be aware that buying extra OEM batteries is going to be almost mandatory. Something that I am very surprised about.

They say compatible but with in a few minutes a full 90d battery started blinking H in the viewfinder. So people that don't want blinking and want full shutter speed won't be happy.

It may not. Like others said perhaps isolated. Today's cams tell you the battery condition. When trouble shooting the answer is always easy. Getting there is the hard part.

Multiple batteries I had trouble with run a 90d in mirrorless mode for over an hour. That's with the rear 3" screen on the entire time.
Maybe that high refresh rate in the viewfinder is really bad.
