You might want to share a minimal reproducible code snippet. The stage selection behavior you mentioned is expected so that shouldn't be the problem.
Also, please try the following first and see if they still hang
- disable cuda graph but enable custom allreduce using your current strategy
- enable cuda graph but disable custom allreduce using your current strategy

it's quite difficult to help custom usage of custom allreduce, I suggest asking @hanzhi713 for help, who originally contributed this code.
