Error: write EPIPE when killElectron

[mzisnm]

Describe the bug
I think it's caused by killing electron multiple times.
Looking at the Bundling log below, it appears that the Bundling process was executed twice.
I added a log line "console.info('stop', currentChild.pid)" to the index.js file before kill gracefully, and this log output twice,The pid is the same both times.
I don't know much about webpack, maybe there's something wrong with my configuration, which is at the back.
To Reproduce
When saving file changes in the src/main folder

Screenshots Bundling log

• Bundling main process...
  ✔ Bundling main process...
  | Bundling main process...
