My site keeps breaking when I add certain WPMDUDEV plugins

I activated WP Smush Pro and smushed my media files which completed successfully. I later started installing a number of other WPMUDEV plugins and while installing and activating these my site keeps breaking. It happened twice in a row now and had to restore my site to get access to admin panel again. Any ideas which plugin may be causing the problem? See my error message I get when I try access the admin dashboard attached.
