    After many successful bakes, baking now fails with this error:

    I'm not sure what is causing this, but this problem has appeared in many versions over the years. Any ideas how to fix this?

    It's the infamous RtlUserThreadStart issue... Hard to tell what could be causing it exactly without taking a look at the project first. Could you please report a bug? Our customer QA will take a look.

    Not sure but I see it is around since Unity 5 and although in the issue tracker I have seen at least 2 claims that it was fixed, it is still affecting people.

    Why can't there be a permanent solution after so many years?
    I understand it is project based, but still...

    It is a big problem as it affects both CPU and GPU baking.

    I will submit a bug.
