Solution：

I experienced the same issue on my Mac and finally found this solution worked for me:

Open your .claude.json in your home folder;

find -name ".claude.json" 2>/dev/null

Add the below line into the json and save;

"hasCompletedOnboarding": true

The complete json after the modification would look like:

{
  "installMethod": "unknown",
  "autoUpdates": true,
  "userID": "[your_user_id]",
  "firstStartTime": "[time]",
  "projects": {
    "/Users/[your_home_folder]": {
      "allowedTools": [],
      "history": [],
      "mcpContextUris": [],
      "mcpServers": {},
      "enabledMcpjsonServers": [],
      "disabledMcpjsonServers": [],
      "hasTrustDialogAccepted": false,
      "projectOnboardingSeenCount": 0,
      "hasClaudeMdExternalIncludesApproved": false,
      "hasClaudeMdExternalIncludesWarningShown": false
    }
  },
  "hasCompletedOnboarding": true
}
