dune utop in emacs is not working

[patrick-nicodemus]

When I open Emacs and run the command opam config exec -- dune utop . -- -emacs, it creates a new buffer which is blank and does not accept text input. If I try to input text, it says "Text is read-only."

If you do this in a buffer which previously had utop running in it, then the buffer prints "Restarting..." and then there is no further output.

If there is no existing utop buffer, then I get the following error message:
error in process filter: let: Args out of range: "", 0, 4

I am using Emacs 30, utop 2.13.1, dune 3.10.0.
