If UEContextReleaseComplete is not received,
the Source-UE will have the Target-UE.
6. HandoverRequired
There may be cases where the Source UE has a Target UE
from a previous HandoverRequired process. In this case,
it is recommended to force the deletion of the Target UE information
when receiving a new HandoverRequired.

... Crashed ...
APER encoding fails when using the asn_uint642INTEGER function on a 32-bit machine as shown below.
```C
asn_uint642INTEGER(AMF_UE_NGAP_ID, 0xffffffff);
...
aper_encode_to_buffer(...)
```
INTEGER APER encode/decode functions seem to be operating internally with long variables instead of intmax_t.
That is probably the reason of the failure.
@v0-e fixed this issues in the mouse07410/asn1c pull request.

o Generate the private key as below.
$ openssl genpkey -algorithm X25519 -out /etc/open5gs/hnet/curve25519-1.key
$ openssl ecparam -name prime256v1 -genkey -conv_form compressed -out /etc/open5gs/hnet/secp256r1-2.key
o The private and public keys can be viewed with the command.
The public key is used when creating the SIM.
