Issues with Jobs package 0.50/0.51 on Unity 2022

I moved a project with the latest Pathfinding package to Unity 2022 and also updated the Jobs package to the latest (0.51.0) and it reports errors in the console and will crash after a Domain Reload. It’s fine though if just using Jobs 0.11.0.

This appears to be related to this change in 0.50.0:

  • Job reflection data ILPP
  • IJob* types use SharedStatic so they can be burst compiled eventually
  • Early job initialization now happens during domain reload rather than delayed until EntityManager.Initialize

The errors in the console are:

Failed to create job reflection data for type $Pathfinding.Jobs.IJobTimeSliced:

And it’ll crash after causing it to reload the domain by changing code or similar.
