I can't get past this step in the docs: https://www.medplum.com/docs/contributing/run-the-stack#start-the-servers When I run

npm run dev

I get this error:

Error: Cannot find module 'C:\Users\alexw\source\repos\medplum\node_modules\@medplum\fhir-router\dist\cjs\index.cjs'

The

npm run build:fast

command succeeds but logs a bunch of errors (attached).
