Hey Anjana,
it looks like it doesn’t find tsc, the typescript compiler. Can you make sure that all dependencies are installed by running

lerna clean
lerna bootstrap --hoist
npm run build

Also a heads up, we recently switched from lerna to turbo. So when you update your development fork you should clean all node_modules (also inside /packages/…) and then simply use

npm install
npm run build
// or
npm run watch
// or
npm run dev
