So I updated my project to the lates alpha and "cant do anything" because of the error in the title. In the NetworkSettings.cs there either of the following lines is used four times: BurstRuntime.GetHashCode64(parameterType); and BurstRuntime.GetHashCode64<T>(); But it seems that BurstRuntime is present in 'Unity.Burst.BurstRuntime' and 'Unity.Collections.LowLevel.Unsafe.BurstRuntime' hence the error. Quick note for others on how to fix this: Copy the transport package from the packages folder to your assets folder and uninstall the package from the packageManager. Then fix the bug by adding Unity.Burst. to the front of BurstRuntime.Get..... . Adding the lowlevel.unsafe.... path doesnt work because the ..<T> isnt present under that path.
