After the release of macOS 10.15.2 two days agao I have upgraded my mac at work to latest version today. Immediately, after running pip to install some packages I was greeted with an abort. I checked the crash reporter to find the offender: Application Specific Information: /usr/lib/libcrypto.dylib abort() called Invalid dylib load. Clients should not load the unversioned libcrypto dylib as it does not have a stable ABI. After poking around for a bit I figured out it was because of the asn1crypto library.
