Unrecognized token error when using #

[nvimtor]

I have this in my init.el:

(setq vertico-group-format
      #("%s" 0 2
        (face my-vertico-group-title)))

It evaluates fine within Emacs, but trying to use it in emacsWithPackagesFromUsePackage results in:

error:

I am new to both Emacs & Lisp so unsure of how to further debug this, or if this at all expected.

Seems to me that #164 is related?

This seems like a problem with the Elisp reader we use, so please file a report there (https://github.com/talyz/fromElisp/issues/)
