Trying to edit blocks I get this error and insted of a wysiwyg editor I get an empty box. If I put the block in edit mode it displays normally though.
The strange thing is that blocks in other parts of the website work normally.

TypeError: invalid ‘instanceof’ operand jQuery
acf-input.min.js:1:29222

TypeError: window.EBWidgets is undefined
load-scripts.php:5:5

ACF version: 5.8.1
