Hi,

the two lines of code, in loadup-el,

(unless (featurep 'ls-lisp)

)

seem to be incompatible with macos (on an M1-processor). With these get the following error message when building the app:

Error: error ("Preloaded advice on pcase--mutually-exclusive-p")
  mapbacktrace(#f(compiled-function (evald func args flags) #<bytecode 0x60dd9c541aed07f>))
  debug-early-backtrace()
  debug-early(error (error "Preloaded advice on pcase--mutually-exclusive-p"))
  signal(error ("Preloaded advice on pcase--mutually-exclusive-p"))
  error("Preloaded advice on %s" pcase--mutually-exclusive-p)
  (and (advice--p (symbol-function f)) (error "Preloaded advice on %s" f))
  (closure (t) (f) (and (advice--p (symbol-function f)) (error "Preloaded advice on %s" f)))(pcase--mutually-exclusive-p)
  mapatoms((closure (t) (f) (and (advice--p (symbol-function f)) (error "Preloaded advice on %s" f))))
  (if (featurep 'ls-lisp) nil (mapatoms (lambda (f) (and (advice--p (symbol-function f)) (error "Preloaded advice on %s" f)))))
  (unless (featurep 'ls-lisp) (mapatoms (lambda (f) (and (advice--p (symbol-function f)) (error "Preloaded advice on %s" f)))))
  load("loadup.el")
