Error on yarn start: ERR_PACKAGE_PATH_NOT_EXPORTED

See original GitHub issue

I checked out the code and tried to run it on the following revision and yarn version:

$ git rev-parse --short HEAD
5bcaa225
$ yarn --version
1.22.19
$ node --version
v17.9.0

I ran yarn to install the dependencies and everything worked fine. When I do yarn start I see the following error and the server fails to start:

$ yarn start
yarn run v1.22.19
$ react-scripts start
node:internal/modules/cjs/loader:488
      throw e;
      ^

Node.js v17.9.0

How can I fix this and launch excalidraw locally?
