npm start and other scripts do nothing [duplicate] - node.js

Question

NPM run * doesn't do anything
(2 answers)
Closed 3 years ago.
Until starting up my computer this morning the following worked:
npm run start
which would run my custom script in package.json and essentially boot up electron with react.
However now running the same command does absolutely nothing. The terminal just returns.
~/myapp > npm run start
~/myapp >
I have tried the following with and without step 3 and it didn't work.
Delete node_modules
Delete package-lock.json
Run npm cache clean -f
Run npm i
Try again.
I have uninstalled and reinstalled node.
My setup is:
~/myapp > node -v
v13.5.0
~/myapp > npm -v
6.13.4
and my package.json is as follows:

Note: I had to add GENERATE_SOURCEMAP=false to the scripts to fix a bug in a dependency.
Can anyone please help?
EDIT:
I just created a completely new project to test the problem as follows:
npm init react-app testapp
cd testapp
npm start
and the problem persists.

Probably ignore-scripts=true was set in .npmrc
Run: npm config set ignore-scripts false
