React Native Building the app, but closing the metro bundler server

my react-native run normally, but he builds and close the "bundler server" and open a very,very old app "version"

Building Successful

max info i have is, i'm running on a device not on a emulator and i'm on linux

i use "npx react-native run-android"

if i try "Reload" the app, it give me the error like is not connect and bla,bla,bla.

i just can run the actual version of the app if i run "npx react-native start"

npx react-native start

when i develop on Windows i use "run-android" and it opens the the Metro Bundler like it does when i run "start" on linux, before i change for 0.60+ the "run-android" did not open Metro Bundler too on linux, but works and still connect to the server.

some one have some idea?
