Incompatibilita con Cost Calculator Builder

Hail!

I would like to insert Cost Calculator Builder into a car rental site but I have the problem that it conflicts with your plugin and gives me critical error if I try to activate it. If I disable Car Dealer, Classifieds & Listing I can load and activate Cost Calculator Builder. If after activation, I try to activate Car Dealer, Classifieds & Listing, I get a critical error. Are the two plugins incompatible with each other, despite being made by the same developer?

I use WordPress 6.6.2 with PHP 8.0 (I have also tested with versions 8.1, 8.2 and 8.3).

Does anyone have any suggestions?

Thank you in advance for any support you can give me!
