    I'm not sure what I'm doing wrong here, but it has kept me busy literally the whole day. Can't manage to fix it.

    I'm trying to update from 2020.1.12f1 (all works perfectly fine in this version) to 2020.3.26f1. When I did this, I managed to fix everything, no compilation errors, but as soon as I try and add a dynamic physics body I get absolutly spammed by the following error:

    Code (CSharp):
    1. IndexOutOfRangeException: Index 0 is out of range of '0' Length.
    2. Unity.Collections.NativeArray`1[T].FailOutOfRangeError (System.Int32 index) (at <d3b66f0ad4e34a55b6ef91ab84878193>:0)
    3. Unity.Collections.NativeArray`1[T].CheckElementWriteAccess (System.Int32 index) (at <d3b66f0ad4e34a55b6ef91ab84878193>:0)
    4. Unity.Collections.NativeArray`1[T].set_Item (System.Int32 index, T value) (at <d3b66f0ad4e34a55b6ef91ab84878193>:0)
    5. Unity.Physics.Broadphase+DynamicVsDynamicBuildBranchNodePairsJob.Execute () (at Library/PackageCache/com.unity.physics@0.5.1-preview.2/Unity.Physics/Collision/World/Broadphase.cs:846)
    6. Unity.Jobs.IJobExtensions+JobStruct`1[T].Execute (T& data, System.IntPtr additionalPtr, System.IntPtr bufferRangePatchData, Unity.Jobs.LowLevel.Unsafe.JobRanges& ranges, System.Int32 jobIndex) (at <d3b66f0ad4e34a55b6ef91ab84878193>:0)
    I get several of these on different locations within the same file.

    Anyone experienced this error before? I tried upgrading to 2021.2.x with the same result. I've triple checked the packages and the dependencies, they are all matched based on the versions. So I'm pretty much at a loss here.

    Packages I'm using:
