It odd you would see that error because that relates to the Widget Customizer which is part of core WordPress, not Connections. Nothing in Connections or any of its extensions even hook into this part of WordPress.

The first error makes mention of arg 1 is not an array… since you’ve already deactivated all but Connections related plugins it is possible that the theme itself is the root cause of the error being generated. I’m assuming the theme does come with many widgets, most seem to? If the theme is incorrectly hooking into the Widget Customizer. It is very possible to incorrectly hook into it and still work correctly with it is accessed directly because of the possibility the theme author did not take into account the Customizer being loaded outside of the core WordPress Customizer features.

In short, any error, even the one you see can cause the Customizer to fail to load correctly.

It is still possible some weird edge case bug in Connections is the cause, even if unlikely, but the only I could determine this is if I am given a temp admin account and FTP access for debugging. I you will give me this access, I will take a look.
