Have you tried changing the baking settings?
Especially the front and rear distance?
Yes I have tried that i have tried 0.04, 0.05, 1 but the problem continues
Could you show your high and low poly in the same scene?
Have you set up a good nomenclature for each part of your mesh in order to bake by mesh name?
No I haven't named the mesh properly but here is an image of my high and low poly model in same scene i have moved the high poly aside so that you can clearly see
I would recommend going through the process of naming each part properly to bake by mesh names. You could at least start with a small portion of your project to test if it solves your issue.
Okay I will try that and get back to you
