The error comes from here: gamipress\integrations\jetengine\includes\functions.php from gamipress_jetengine_check_type() function
It creates a new instance of Jet_Engine_CPT class and assigns it to $post_types_obj variable, instead of using jet_engine()->cpt to get an already existing instance
So it should be changed from this https://prnt.sc/HkrROSNM0-ex to this https://prnt.sc/yinz3CkxlbKW
