:noweb yes breaking ob-async with error in process sentinel: Invalid read syntax: "#"

Checklist

• I followed the troubleshooting guide and it did not address my issue

• I've included a link to a Github Gist with the full contents of my troubleshooting.org buffer

• Each section below is filled in and includes sufficient detail to reproduce the issue

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 #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

I'm dealing with the same problem (I'm on Emacs 29.4, org 9.6.15). After launching emacs --no-init-file executing consecutively the following blocks of code results in the same error.
@bschwehn Did you manage to solve problem? BTW. Is ob-async dead? The last commit was 4 yeas ago, the last issue - almost year and a half...
