Lazy Loaded Modules with AOT - TypeError: '' is not a function when served from NGINX

It's because when you use AOT, the code is uglified with some funny UTF-8 symbols; ɵ in i0.ɵcrt in your case

You need to tell nginx to use UTF-8 charset

server {
  listen 80 default_server;
  listen [::]:80 default_server;
  server_name _;

  charset UTF-8; #<==== Add this
