Lately involved side-channel makes the whole lib not working.

Pls double check this. It cannot work through this line.

I'm not sure what you mean - the library works fine. Your screenshot doesn't make it clear what the problem is; it just shows two breakpoints.

If you're using webpack 5, however, you may not be aware that it's broken by default - you'll need to fix it to polyfill node globals so that it's a working node module bundler.

In other words, I'm assuming this is related to inspect-js/has-symbols#11, which is actually solved in the latest version of has-symbols (make sure your lockfile is properly updated).
