muon would quit if 'userData' path is not exist

[miaulightouch]

• muon version: 5.0.6
• Operating system: Windows 10

// set userData path manually, muon is not using package name as path to save user data.
const userDataPath = path.join(
  app.getPath('userData'),
  isDev ? '.' : `../${productName}`)

// set path
app.setPath('userData', userDataPath)

muon would be closed by itself if the path is not exist. even muon created the folder.

I must add these code before set path

// create folder manually, muon won't create this properly.
fs.existsSync(userDataPath) || fs.mkdirSync(userDataPath)
