Answer 1

It can be difficult to determine the specific source of the problem, but there are a few things you can try to resolve it:

1. Try using git diff --name-only --diff-filter=U --relative to check for merge conflicts and list the files causing the problem.
2. Before running npm run dev, try running npm ci.
3. Try to newly clone the project in a different location and run npm i on the master branch, then run npm run dev to see if the problem persists.
4. Check that you are using the correct Node version that is compatible with your project node -v.
