problems with a project in Unreal Engine 5.4

I have a project in which a rocket follows the Splines to follow its path.
I made the project in Engines 5.1 to 5.3. Then I decided to put the rocket in UE5.4.
However, in this version of the Engine the Rocket does not work as it should.
There is a part of the path where it simply gets lost and after some time it returns to its normal path.

I have already tested a lot of things and nothing has fixed the errors.
Could someone help me?
