Exception: According to the loaded plugin descriptions the class smac_planner/SmacPlannerHybrid with base class type nav2_core::GlobalPlanner does not exist. Declared types are nav2_navfn_planner/NavfnPlanner smac_planner/SmacPlanner smac_planner/SmacPlanner2D

Why ı cant use nav2_smac_planner/SmacPlannerHybrid, nav2_smac_planner/SmacPlannerLattice and Theta Star Planner.

Theta* is not available in Foxy, its only in Galactic and newer. Smac Planner was originally backported to Foxy, but before the State Lattice Planner so the naming is a little different. See the migration guides: https://navigation.ros.org/migration/index.html. Note that the Foxy version of Smac is somewhat out of date, so some bug fixes or new features have been added that are only available in more recent distributions.

The Hybrid planner is the just SmacPlanner in Foxy. Ther is no Lattice or Theta*
