I'm experiencing the same issue. ```split-string: Wrong type argument: stringp, ("ELisp" (lexical-binding (:propertize "/l" help-echo "Using lexical-binding mode") (:propertize "/d" help-echo "Using old dynamic scoping mode mouse-1: Enable lexical-binding mode"...

Also need to put (mu4e--send-harden-newlines) instead of (mu4e-send-harden-newlines)

I'm experiencing the same issue - and updating Python and Emacs packages is not solving it.

I don't understand - how did you solve it @EmmanuelCharpentier ?
