    Unbelievable, this bug has seriously affected production, and now most of my project's asynchronous code can't work.
    Yes, I know. If you don't lose your temper in the forum, then no one will pay attention to you.

    I Just encountered/reproduced this and would also love to see this backported, as it seems 2019.2 is a ways out, and we are using async functions on current released builds

    We are using unity 2018.3 with async methods and we really need this to be backported.
