ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1] handle an error

I wanted to deploy Data Guard today, but an error was reported when the slave database was started:

ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], [], []

The alert. log alarm section is excerpted as follows:

Errors in file/u01/app/Oracle/admin/orcl/udump/orcl_ora_5642.trc:
ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], [], []

Orcl_ora_5642.trc is extracted as follows:

The final problem is that the hostname has been modified and the host can be changed back.
