My homepod the ligth keep flashing red and cant do anything Im already try to reset on the phone and they not appear again .

You should reset the HomePod. This article explains the process. There was an update for the HomePods in the latest iOS release so you may take up to 20 minutes for it to download and reinstall the update if they had not been updated yet. Just give it some time to do the install and don't stop the process if it says it is installing.

There’s an Orange flashing light when HomePod mini is connected to a computer, or is plugged charging into a power adapter that isn’t rated 20W (9V ⎓ 2.22A) if it’s a HomePod mini and you’re seeing this please use the charging adapter Brick it came with.

Or a Red spinning light when you're resetting your HomePod speaker?

Which is it ? There is no flashing red.
