WP 5.9.9 – Ninja 3.3.17 – Js error make impossible to switch to email

I go to Ninja Forms -> Dashbord, choose a modules to edit and start modifying it

I cannot switch to “email and actions” tab, and neither to “advanced configuration” (please note, I’m using in italian, so english tab names could be little different)

I’m facing this error on javascript console when clicked on the tab nam
