*Geiser Guile REPL* buffer doesn't return prompt anymore

Hello!

I've been having this issue since a couple weeks where evaluating anything at the Geiser Guile REPL doesn't return the prompt:

GNU Guile 3.0.8
Copyright (C) 1995-2021 Free Software Foundation, Inc.

Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'.
This program is free software, and you are welcome to redistribute it
under certain conditions; type `,show c' for details.

Enter `,help' for help.
scheme@(guile-user)> (display "test\n")

The pointer flashes on the last line, but it never returns.

What could I do to debug this? I'm using the emacs-geiser 0.28.2 and emacs-geiser-guile 0.28.1 packages from Guix, atop emacs 28.2. Native compilation is enabled.
