[emacs18]

I can't find any use of lexical-let within spacemacs or emacs 29.

Also revision 844de3153 does not seem to exist within spacemacs git repo.

I cannot reproduce your error, however from your stacktrace I can see that your issue happens in exwm not in Spacemacs. Please retry without exwm and reply here. I have made a small change to fix the setup of exwm for the latest version which was referring to an obsolete exwm-config file.

Unfortunately I cannot test with exwm as I am running a pure wayland build.

Indeed. No issue with an installation from scratch. :small_airplane:
