Display Pack breaks Calendar Editor

Hi,
I updated the plugin and add-ons to their latest versions today and noticed the admin Calendar Editor stopped working.

The following messages is shown

A fatal error occurred. Please try to refresh the page. If the error persists, follow the process under “Booking Activities doesn’t work as it should” here: FAQ.
Advanced users, you can stop loading and free the fields to try to solve your problem:

I followed the guidelines and everything works fine whenever I deactivate Booking Activities-Display Pack add-on.

Any tip that would help us to continue using the Display Pack without this issue would be greatly appreciated.

Thank you in advance,

Paulo
