Fresh React Native App won't install on emulator when I run "npx react-native run-ad"-CodePudding

I have a fresh app built with React Native CLI using the "npx react-native init LatinApp" command and there is nothing edited in any file. When I run the "npx react-native run-android" command in cmd, it opens Metro in another cmd but it throws the following error. (I ran my cmd with administrator privileges and all files inside the android folder have Full Access enabled)

CodePudding user response：

The problem was with AVG Antivirus, it flagged the "manifest-merger-blame-debug-report.txt" as a Trojan for some reason. Disabled that and the build finished successfully.
