Character locked in place for a while after setting new location

I’m following this youtube tutorial on how to create a zipline. My setup is exactly as shown, yet at the end of the zipline my character is running in place when I try to move. Jumping yields the same result, I can’t go anywhere for a few seconds and then it lets me move again. Anyone have the slightest idea as to why? I can’t seem to figure this out. Any help would be greatly appreciated!
