Critical error

This is a problem that i have with both this plugin and the ‘advanced local pickup’ plugin.

When i go to the customizer it says there is a critical error with my site. but there is nothing wrong with my site! I already tried deactivating all of my plugins and it did not work. how do i solve this?
