[The following patch might help (it solves a similar problem on a Linux
 TTY), but this is unlikely:


diff --git a/lisp/frameset.el b/lisp/frameset.el

After starting Emacs, which fails as above, could you possibly do

    M-: (frame-monitor-attributes (selected-frame))

and post the result here, please.
