This looks to be a scratch on a lens element. Please contact customer support for an exchange and so this unit can be torn down to find the root cause.

I doubt that it's a scratch on a lens element. I have often seen the same linear streak on photos from mobile phones. I wonder if the streak is an artefact caused by whatever comprises the aperture in these small sensor camera modules.

I think I'm agreeing with that, function of Lens/Sensor size combo. But so strange it "disappears" before returning.
It's a super sunny day today, might test/compare my RX0 vs RX0M2 vs RX0M2 and further test the 2 GPH10B's.
Maybe try the 11B in portrait mode.
I did watch the GoPro release promotional video for the 11B. You could see it show up in there a couple times. (but not as bad, since they were using the wide views I believe).

Landscape
Kind of felt like top right and bottom left were largest.
Portrait simply rotated it as expected.

Are those taken WITHOUT the lens cover glass? If they are, it's not a lens element scratch, as those are localized.

You can get streaks like that from apertures with rough edges, but a lot of work went in to significantly improving that in GoPro cameras some years ago using some apertures with a special technology from a Japanese supplier.

It's not a lens design issue. It appears to be a test escape.
As GoPro's Director of Optical Systems, I can tell you that we care very much about it. That's why the correct course of action is to contact customer support and to send the camera back so my team can tear it down and find the cause of this issue,

To be fair, I have never seen that streak on output from my own GoPro 8.
I'm sorry you are having this issue. It doesn't show up on my 11 Black. I don't know if this is correct or not, but apparently there is some sort of coating on the lens cover that allows water to run off leaving no drops. I wonder if the coating is not applied properly. Sorry, I guess I'm grasping at straws here. If you have additional replacement lenses such as ND filters. Swap for one of those and give that a try.
That sounds like the proper course of action to me. It sounds like an internal problem, as my 11 is not affected. I thought it might be an issue with the coating that repels water, but I guess its not.

I removed the lens cover in the post above labeled as such, and it still shows up.

I'm not sure of your exact test, but good to hear you don't see it.
I'm not pointing at the sun generally, so I'm not too concerned for this camera. I'll probably buy another one at some point in the next year, maybe that one will be better.

I am not seeing it either - and I am pointing at the sun a lot.
Why not contact support, they will certainly give you a new camera if you send that one back - free shipping both ways.

If I was to make my own post there, it would be the same type of response:
"enriquezae (GoPro)3 hours ago
Hey, @mzoslater. We have not had this issue reported to us before, and we'd like to gather more details. ".
been using GoPros since the 3. I've found that it's better to just try to solve things on your own where possible rather than get irritated with them. Most of the folks you can reach operate off of scripts.
Heck it can even be nearly impossible to place an online order with them. Great product if you can work within such limitations and have a certain kind of attitude tho. I have many of their cameras and accessories.
From what I can see so far...it could be a lens issue further down in the assembly, perhaps related to changes to welcome the taller sensor. It is something simple. For example if you can get the lens off (possibly unscrew the actual lens like on so many early gopro, leaving the housing as-is), some tweaks may be possible if it is internal reflections. Or not.

That's quite pronounced. I don't get that at all on my 11.

While not perfect, is it such a big deal? As I remarked, mobiles (ie cellphones) do this a lot. Most people won't notice let alone care.
Personally I am not at all concerned.
On cell phones doing the same flaring...many also overheat very easily in the higher video modes, especially in the Sun. Heck in NC they overheat before you even start a two hour continuous clip after fast-charging them with sunlight hitting them. Or just Sun. Faster than GoPros do, since larger surface areas to absorb all that heat from the environment.
