Windows Taskmanager multiple instances of Electron

Yesterday when i took a break from coding and all programs closed, my machine kept running.
When i checked windows taskmanager i seen 4 tasks of Electron running in the background eating resources.
I wonder if someone knows how/why?
I not made a nativephp:build yet (not that far lol). Only used nativephp:serve.

Not yet sure, but happens when i run the app with high tasks.
In my case a 35MB what needs to be read, and inserted to SQLITEdb.
Now i use smaller files for testing/dev.
Everyting quiet now.
