This works for npm run start in win11, and will prevent cmd.exe window popup:

module.exports = {
  apps: [
    {
      name: 'qq-bot',
      // script: 'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js',
      // instances: 1,
      // exec_mode: 'cluster',
      script: 'npm',
      args: 'run start',
      cwd: 'D:/repo/qq-bot',
      interpreter: process.platform === 'win32' && 'C:\\Windows\\System32\\cmd.exe',
    },
  ],
};

I tried C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js with fork mode and it will popup cmd.exe.

I tried cluster mode, but it won't execute things in npm script, if that script point to a ps1 or bat shell file in node_modules/.bin

But with interpreter cmd.exe + script: 'npm' this works well.

Research direction

No repository file or test is named. Start by reviewing the linked issue and the Windows process handling involved in npm run start, then reproduce the fork and cluster cases on Windows 11 with cmd.exe, npm-cli.js, and scripts using .ps1 or .bat files. Done should establish the supported behavior and prevent the reported cmd.exe popup.
