For some reason our BP_Third person Herb is not recognised within our blueprint and I want to know why please help

Working on a team project currently, and for some reason our BP_Third_Person is not being recognized by the system, how would we solve this issue?

Type mismatch.

You are casting player character to bp_thirdperson_herb

just to be sure is bp_thirdperson_herb is player character class?

Can you close all tabs and send screen shots of your herb
