That error is generated by emacs when it tries to spawn a process, and
then canʼt find it. Iʼd search for `call-process' or `make-process',
in flycheck and/or proselint and see if the program itʼs trying to run
can be found by emacs using `executable-find'. If not, you may need to
adjust your `exec-path' or a configuration variable.

You could also try setting `debug-on-error' to t, but I guess flycheck
might trap errors.
