Expected Behavior

Async execution working or at least only failing once when using :noweb yes

Actual Behavior

After executing a code block with :async and :noweb yes, all subsequent executions with :async fail with error

error in process sentinel: async-when-done: Invalid read syntax: "#"
error in process sentinel: Invalid read syntax: "#"

Steps to Reproduce

execute

#+begin_src shell :async
echo ff
#+end_src

=> this should work asyncronously

execute

#+begin_src shell :async :noweb yes
echo ff
#+end_src

=> this fails with "Invalid read syntax: "#"

now

#+begin_src shell :async
echo ff
#+end_src

also fails and keeps failing until restarting emacs.

I have tried the workaround that was suggested in https://github.com/astahlman/ob-async/issues/75

(defun no-hide-overlays (orig-fun &rest args)
  (setq org-babel-hide-result-overlays nil))

(advice-add 'ob-async-org-babel-execute-src-block :before #'no-hide-overlays)

but no difference
