That shouldn't be necessary -- "emacs -Q" will start an Emacs without
any local customisations.

I'm unable to reproduce the problem in Emacs 27.2 (or 28).  I said:

emacs -Q
M-: (open-line -1)

And then I just get this backtrace:

Debugger entered--Lisp error: (error "Negative repetition argument -1")
  self-insert-command(-1)
  newline(-1)
  open-line(-1)
  eval((open-line -1) t)
  eval-expression((open-line -1) nil nil 127)
  funcall-interactively(eval-expression (open-line -1) nil nil 127)
  call-interactively(eval-expression nil nil)
  command-execute(eval-expression)

I don't see that, either.  What does `C-h f open-line RET' say for you?
