Hi @华的唯一 ,
welcome to the Atlassian community!
Based on your screenshot you are running a very old version of jira. Jira Agile is now Jira Software and it is a jira module and no more an external app.
BTW, please share with us the log entry placed in the atlassian-jira.log file in your JIRA_HOME folder so that we can figure out what is happening.
