Problem & expected behavior (under 200 words)

The stackblitz will work if moving back to tsx 4.11.2

Basically using

"imports": {
    "#*": {
      "production": "./dist/*",
      "default": "./src/*"
    }
  },

in package.json no longer works in 4.12.0

I assume commit 72d0896 is responsible for the issue as a path starting with '#' may not be considered a unix path?

Bugs are expected to be fixed by those affected by it

• I'm interested in working on this issue

Compensating engineering work financially will speed up resolution

• I'm willing to offer financial support
