yarn build fails after fresh yarn install

Ran into the following error when trying to build from scratch:

yarn run v1.22.5
$ react-scripts build
Creating an optimized production build...
Failed to compile.

I think it's related to this commit https://github.com/DefinitelyTyped/DefinitelyTyped/commit/cc251bdaf2ec2626bacb1c097334b8a36f43c0d4#diff-dcca2fdd8c0717a0e2e771661ec424a8a81899b5d35ec0d33afd7c588ccd1778 where they removed PoorMansUnknown.

As a work around I installed @types/history@4.7.7 , but the interface should probably be updated to work with the new version.
