Comment (by jamiepmg):

 Just found this article when Googling our issue, which sounds identical to
 Jane's: in WP 5.8, Widgets have upgraded to a block editor version, which
 takes an extraordinarily long time to load, and then displays about two
 dozen errors (https://www.screencast.com/t/iinPQwaJUw). We're unable to
 edit any widgets. In Chrome, the Developer Console shows dozens of JS
 errors, related to widgets.php and widgets.min.js
 (https://www.screencast.com/t/OCEpwRAaEMv). Client reports widgets worked
 as expected last week.
