 @csuerj Welcome to Trac!

 I recommend reading through the following list of potential issues with
 5.5: https://wordpress.org/support/topic/read-this-first-wordpress-5-5
 -master-list/

 The most likely issue is that a plugin or theme on your site is running
 old JavaScript code. Could you try installing and activating this plugin:
 https://wordpress.org/plugins/enable-jquery-migrate-helper/

 This will confirm that there is JavaScript on your site that needs to be
 updated to follow more modern jQuery practices. You can leave the plugin
 active for the time being, but the breaking code will need to be updated
 before the next step of the Upgrading jQuery in Core roadmap.

 If this does not fix the issue, please follow up in the support forums
 above as mentioned by @jrf.
