Workaround
When you upgrade the oscrypto package to the newest version 1.3.0 this error disappears, but a new error appears, because it automatically upgrades the as1ncrypto package, which isn't compatible with the django-aspy2 package. If you downgrade the as1ncrypto package after the upgrade to version 1.4.0, it works.
oscrypto==1.3.0
as1ncrypto==1.4.0
