Nx on Windows fails to run any tasks for monorepo

[molisani]

Current Behavior

For any commands that run project tasks, the following error is reported:

 NX   Cannot read properties of undefined (reading 'allWorkspaceFiles')

This is only happening for our monorepo for users running from native Windows.

Expected Behavior

Expect the tasks to run as they would in WSL or macOS or native Linux.

Internal Repo

Steps to Reproduce

1. npm ci
2. npx nx run-many -t build --verbose

Running npx nx show projects also fails, but it just doesn't print anything and ends without error.

Additional Information

This appears to be some kind of issue with the task hasher and specifically the externals argument passed to InProcessTaskHasher and NativeTaskHasherImpl. Because this repo does not have strictNullChecks enabled, this property can be null when passed to NativeTaskHasherImpl which does not expect it to be null/undefined. And when storedFileMap is null-ish here that value is always null.
