Bug / Crash Compatibility to Unity 2023.1

[ImpossibleRob]

Thanks for the fast response! Highly appreciated. I did the changes but some errors still remain. I am now on 2023.1.b5, Collections 1.2.4, Burst 1.8.2 and Mathematics 1.2.6. The compile error I get is

Code:

Obi\Scripts\Common\Backends\Burst\DataStructures\NativeMultilevelGrid.cs(87,16): error CS0246: The type or namespace name 'NativeParallelHashMap<,>' could not be found (are you missing a using directive or an assembly reference?)

What can I do about this one? Thanks a million!
