I have a cylinder with some Boolean modifiers , all applied , i have added proximity loops to some of them and as all Hard surface Projects have it , this one also needs a Bevel modifier which i added and here is the difference between Before-Bevel-Edge and After-Bevel-Edge Providing Link for Reference to the original file

so , Q: How To Fix this?

Edit - The check box Clamp Overlap is intentionally so that i can control the bevel amount but if i see in josh gambrels tutorial on this thing , he doesn't have any such problem

    $\begingroup$ there's a checkbox in your screenshot, clamp overlap. If you check that it prevents the overlap, but also limits your offset. Isn't your object already beveled? Try also to increase the limitation angle. $\endgroup$ Commented Oct 17, 2020 at 14:00
  • $\begingroup$ @FrederikSteinmetz I was watching Josh Gambrels Hard Surface Modelling tutorial and i have disabled the Clamp overlap and reduced the Bevel Amount as mentioned in the tutorial and He didnot have any overlapping problem when he did the same thing... $\endgroup$ Commented Oct 17, 2020 at 14:51
  • $\begingroup$ @FrederikSteinmetz i did not bevel it but YEAH!! looks like it is , could this be the problem , probably while applying the Booleans , i might've messed the bevel modifier? $\endgroup$ Commented Oct 17, 2020 at 14:57

Your angles are not made of just one edge, they are already beveled:

So your modifier will double-bevel these edges and mess everything up with overlapping faces.

You can fix that by a Merge by Distance for example (be careful to not merge what you don't wnat to merge though).
