Navmesh Pathfinding Freeze (may be a while loop thing)

I have a scary creature following my player around. He likes to teleport somewhere behind you when he can no longer pathfind to you. That's what the script below is designed to do. My intention is to have to have this script perform the following behavior: if he can't pathfind to you he teleports to an area behind you, waits a second and then chases you. I had to check his pathfinding using a simple "see if he's standing still for too long" check. He actually performs perfectly! but... If the player character spends too long off of mesh, the whole game freezes!!! I thought it had to do with the navmesh components, but I feel as though I could have just messed up this while loop somehow...

I have messed with these 100 lines for so many hours I can;'t even see them any more. And yes, I have isolated the cause of the freeze to this specific script. If you have any other advice, I do appreciate any. I'm new so thanks! Any help is appreciated!! Thank you in advance!
