Faulty upgrade

Hello, I have two websites with different server configurations with the latest version and both have the same reaction and I can not get a display of new events and found the following error when trying to create a new event just in one of them: Call to a member function rp_id() on null

The other one doesn't show any information or error.

Appreciate any help.

This is the config for the one that show the error:
