I am trying to do updates but it just keeps looping. It need to update Upfront but I can't.

This is the message I get: You have successfully updated Spirit. Unfortunately, this theme update isn’t compatible with your current version of Upfront so it’s important that you update to Upfront 1.0 now to keep your website running smoothly.
Fatal error: Access to undeclared static property: WPMUDEV_Dashboard::$ui in /homepages/35/d344764258/htdocs/clickandbuilds/edreamsdesign/wp-content/themes/uf-spirit/compat/admin.php on line 35

I also can't update to the latest WordPress theme and on my website it shows:
