UE detach issue in 5G SA after completing all steps

Hi Experts.

I’m getting UE detach issue in 5G SA.

After completing all steps, but before PDU session request, it’s getting UE context release command.

Any suggestions pls to over come it?

Check the reason why AMF sending ReleaseCommand.

It’s CU that is initiating UE context release.

But do not understand why…
