The use of std::map find is throwing compiler error C2675 and I can't figure out why

Why is my find failing to compile for the class below? Error reads: Severity Code Description Project File Line Suppression State Error C2675 unary '++': '_Iter' does not define this operator or a conversion to a type acceptable to the predefined operator PlayspaceForDataStructures C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.33.31629\include\xtree 1259
