Does anyone know what this is?

This appears randomly. I don't even know which app is causing this to appear?

I think it's the symbol for when you've cast to a TV. I get a similar symbol when my phone asks me if I want to cast to my TV if I have you tube on.

@smg1  Certainly looks like the casting symbol.  A list of symbols here https://www.samsung.com/uk/support/mobile-devices/what-do-the-different-indicator-icons-mean-on-your...

I think it's a casting symbol but red. Which means it's not connected.

Looks like casting icon to TV or smart monitor. Also google home this will come up.
