As a fellow user, I can tell you the main solution is the same for any plugin that seems to have crashed your admin and that you want to disable. You have to go into your site’s hosting account (CPANEL, if you have it) to edit the directory where the plugins are stored, and just delete that plugin’s directory OR just rename the plugin directory something else temporarily (but this would disable ALL plugins at once). That will let you load your admin. No plugin is going to be able to give you a fix for your setup if you can’t even get into the site.
However, FYI, since NGG has 800K active users, it is highly unlikely that NGG “broke” your site on its own or it would be breaking a lot more sites. Far more likely is that your site has bad designs in its theme or other custom plugins, and when you activated NGG, those conflicts suddenly crashed your site because they are not fully WP compliant. Not NGG itself.
Equally, it would be even odder for NGG to crash your admin side of things. It might crash a page, a post, a gallery, etc., but your admin side? Not unless the update was somehow corrupted. Unless again, you have some sort of custom plugin that is actively managing your admin side perhaps or you’re running a custom theme you designed in Elementor or Divi that isn’t entirely compliant? Even then, it shouldn’t affect your admin side. I assume you’ve cleared all caches too. When you do get back in, you could try switching to a default theme like Twenty Twenty and reactivate NGG. You’ll at least know what it is conflicting “with”.
I’m also assuming though that you have ensured your site is running the specs for NGG, including the right versions of PHP.
Good luck, maybe official support has a better solution…
