Build ExpoGo APP : Nexus RM Connection Refused - react-native

Question

i am new to web and in general development at all and sutmbled upon the following error where i hope you could help me out with.
I have upgraded the Expo SDK to latest version 45
I have checked all dependencies and deprecated version etc.
I have run all commands as instructed and tried to
3.1) Run App locally with following error
Error: C:\Users\sp\AppData\Local\Android\Sdk/platform-tools/adb exited with non-zero code: 1

3.2) As i build via e.g. eas build -p ios --profile development following error appears
[stderr] error An unexpected error occurred: "http://localhost:8081/repository/npm-group/#expo%2fsamples: connect ECONNREFUSED 127.0.0.1:8081".

yarn exited with non-zero code: 1
Note: I have created a NPM_TOKEN secret and added ".npmrc" File to my root directory including the _auth and registry information to connect to my nexus rm.
Any ideas what i am missing?
My actual package.json looks as follows

As mentioned i am completely new to web development, expo and any similar form and the project was just copied from a previous source so i had to set up the env myself as well after cloning so forgive me if I am missing out on something here.
Thanks and appreciate your help! ! !
