When the module is enabled, trying to place a block in any region of the Block Layout page results in the error below, which breaks the Ajax of the "Place Block" option.
I'm using Drupal Mega Menu 1.14.0 and Drupal Core 9.5.10.

Hello,
I'm not sure if this is the solution for every case, but it's worth a try.
I had exactly this problem on a customer's site who installed the module with the backoffice module manager.
I completely deleted and reinstalled it with composer -W (updating all dependencies), and the problem disappeared.
I am not getting any error with Mega menu version 8.x-1.16 and Drupal version 9.5.11.
