Mobile Menu does not works in WP 5.5

Hi all.. Since updated to WP 5.5 the mobile menu of Catch-Katmandu on two sites does not works.. Every item You click the site always reload the home page.. Using the plugin Enable JQuery Migrate Helper the menu works in the proper way.. I've updated the theme two times but the issue is not solved.. On the WP Supporto Forum @pratikshrestha says that sites works but this is not.. Could You help us..? Thank You P.S. Now sites works because the plugin is active
