@EgorBo - were you able to identify? I looked at the dumps and AV seems to be in generated code, but was not able to get all the symbols. In case you are busy, let me know and I can take a look.

Sure, feel free to take over! 🙂

This no longer repros on main. I tried to repro it with artifacts from pipeline and the newly built System.Numerics.Tensor.dll and they don't fail anymore.
