    I am getting this error in the editor now when using blobs inside a burst job:

    Just out of curiosity, how did this happen? Do you work with a version of Burst that now supports try and catch or someone was quite reckless?

    Dots itself only has unit tests against blob data which don't use burst.
    In physics the error didn't show itself with safety checks disabled.

    Overall the real problem is that we don't have a cross package repository CI system that continously checks all different packages and dependencies against each other. It's complicated because we have now have a bunch of different combinations.

    We are working on it and once we have it is should significantly reduce any issues where packages are incompatible as well as improve pain from discovering issues late resulting in delayed releases.
