Yes. It can. Taking pictures will make it overheat to a point where a white warning sign appears. When that happens further pictures will have lower quality. Check out the online user guide, page...

You can take photos when it overheats. But the image quality of the photo will be affected.

Let's not forget overheating will affect still image quality too. This is well documented in the R5 user manual.

I'm worried about Panasonic and even Nikon.

And Sony releases a7s3 after that, which might be more reliable than the overheating R5 for AP jounalists.

Canon Japan: Due to increased cancellation of of pre-order, EOS R5 & R6 are no longer in short supply !

I hope the heat wouldn't damage the hardware.

It's not intended for professional movie makers. It's for enthusiasts, like an overclocked computer for gamer. It's too unstable for professional use.

If you want supreme quality 4k video, with high DR and ISO performance, go Sony. If you really need 8k video, buy the Canon R5.
