A friend of mine is having an issue with steam/dota 2.
He tried Dota 2 the other day, and ever since then, Dota 2 will always launch by itself, but not actually opening.
He said it doesn't appear on task manager or in background processes.

Any ideas what could be causing this?

That's simply impossible. Tell him to check the details tab in task manager (if he uses Win 10).

Said he has, and theres nothing there related to Dota 2 or Steam.

It is possible - Steam recognises the game as already launched, even though it's not. Because the program thinks that the game is being played at the moment it doesn't let you launch another game (or the bugged game for the record) and instead shows you "the game is already launched" error. At least that's what happened to me and McNally seems to be describing the same bug (please correct me if I'm wrong).

Then it's not actually running in the computer, try the log out method described by Hawkeyebrow below.

The Windows task manager only shows the processes running locally so it will never show this kind of behavior.

I had similar issue in the past, but with another game. My guess is that it's a steam bug since I found a soultion online. I think logging out and back into steam account helped, but I can't remember properly. Could you tell him to try that and see if it works?

I don't get what you are really saying... so when they start their windows and opens steam it just opens dota 2?
re-login, reinstall steam, update steam, update dota, validate missing files, trouble shoot, all of these might help tbh

it launches itself but not actually opening and is not in the task manager too,
