Do not use loader in entry, it will be error in webpack@5

@evilebottnawi It works currently for js files, so it dosent really make sense to me why js works just fine and ts is not working because of the changes in the next webpack major version. Also there was nothing about "consider not using loader for entries" in the changelog of 1.0.0.

Anyway bug in thread-loader, you can remove thread-loader and all works fine, can you open new issue in thread-loader?
