Question Job to spawn entities runs in Editor but not in Build

I tried to adapt this official entities tutorial to display sprites instead of the tanks.

TL;DR : I can create and render entities with a system + IJobEntity + bakers and all that good stuff correctly in the editor, but the entities are completely non-existent in a Windows build.

So, I am sure there are many things not optimal about the way I am doing this but it just a huge red flag that it isn't building correctly and I just can't figure it out. This is what it looks like in the editor:



The player from the build only has the cube. No error messages in the attached debugger.

I added the cube to make sure that the scene was loading correctly. I added the repro above to try to save a bunch of screenshots and code snippets but after attaching a debugger to the build, but I know that the job to actually create entities is not executing. I just have no idea why.

Any insights at all would be incredibly appreciated!

 

This has been solved, but I still don't quite understand why.

The issue was essentially that the Job Scheduling was not working on the first Update call for the System. So, on the first update, I called ScheduleJob X times, I increased the count of the number of sprites I thought were spawned by X, but the jobs were never scheduled and no sprites were spawned.

Replacing this with a query works, but it is still unclear why it took 10 frames for the job scheduler to work.

 

Subscenes load asynchronously in builds, whereas in the editor they are preloaded.
