Unity always crashes when importing a package

Every time I happen to import a package, Unity 5.6.6f2 (32-bit) crashes, and opens up the bug reporter. However, when I open up Unity again, the package is successfully imported. Is there a way to fix this?

Hi @duhc ,

This issue related to the old package format. This forum is about the new Package Manager.

Could you please submit a bug: Unity QA: Building quality with passion

Thank you!
