Basically it looks like windows bug on react packager. When you disable Hot Reloading, it should be stopped. If not, can you try "npm cache clean" before run "react-native run-android", please? Also you can try to run on administrator. If these are not working, maybe it's about Antivirus app.
Also can you add ".idea" folder to your github ignore file to try? And are you trying to run it from Webstorm (or any eclipse-based platform) directly or terminal?
