Failed to load config "react-app" to extend from (on build)

I returned to a project after a while and used npm-check-updates to upgrade all packages. I am now receiving the following error on build:

Failed to load config “react-app” to extend from.

I have tried running ionic repair to no avail. I also created a new ionic react project to compare the package.json files but nothing jumps out. I tried manually installing react-scripts and the typescript eslint packages but that didn’t work either. Any ideas?

Here’s my package.json:
