After tsc --build

ERROR:

I think problem in package.json.
May be replace 'main' to 'module'?

This project works fine in TypeScript.
This project is ESM only. 1 in 10 packages on npm are now ESM only, and it’s rising. You can find many resources online on how to use ESM.
I am not going to change this project.
