This seems like something that just happens, so that's not that
unusual.

I'm sure you have an answer that says this, but this message says it
all, though maybe a bit obscurely...  The directory `/run/user/1000` is
not owned by the user ID `(uid 0)` but by `uid 1000`.  You are running
the command as uid 0, or root.  Which you acknowledge you're doing.  It
says the important thing at the end `Don't do that.`.  

You need to run it as the user who is logged in to X (or Wayland).

This is a temporary directory which is created on login (I believe
that's when it gets created).  Don't change the ownership of it.  The
problem is the user you are running the command as, isn't correct.

Probably because your user 1000 is trying to access something that only
root can access.  But it's not entirely clear.  The changing ownership
of /run/user/1000 to root, will break *lots* of things.  Especially
don't do that.

I hope you got this sorted.
