WAIT !!!!
1. acf_form_head() processing form after send it.
2. IF your js error block your console before sent form you have still problem.
try fix it that in your JS:
acf.o = {};
acf.screen = {};
acf.o.post_id = 0;
acf.screen.post_id = 0;
Js console should by clear now. You could work in js and create fileuploader and gallery.
Soon I’ll add code to frontend jquery uploader based on this library:

Now I testing it.
