It might be issue cause, group_id should be unique in system.xml and crontab.xml files.

Did you enabled any custom module, please try to disable it and run upgrade/ cache flush command.

Already found. Thanks for your reply.

The issue is on cron_groups.xml

This line was missed on group "<use_separate_process>1</use_separate_process>"
