Build hangs with yarn pnp

[DiFuks]

Current behavior

When I run a build with yarn pnp (and pnpEnableEsmLoader: true) the process hangs

Expected behavior

The process does not hang and completes successfully

Steps to reproduce the issue

1. Install yarn 3 with pnp
2. Install webpack 5
3. Install fork-ts-checker
4. Run webpack build

I am also running into this issue. I tried the steps outlined and confirmed setting pnpEnableEsmLoader to false lets the plugin run properly.
