    No, I gave up on it. In my case the offending code is not in a pre-compiled assembly, however my setup is a little weird.

    Basically, I have a base abstract class that inherits from ScriptableObject that IS within a precompiled assembly. There are two implementations of this, one in the assembly as well that does not use Burst, and one outside that is basically the same code but with the BurstCompile attribute. However, I have tried changing the names of the structs (before they had the same name across both implementations), but that doesn't fix the issue.

    So this may be related to using a pre-compiled assembly, but I'm still not sure how.

    For your information, in my case, the problem was compiling with Burst code in a precompiled assembly.

    Also running into this, did you find a workaround or identify the root cause?
