Resolved Burst compiler exception within HDRP 12.1.6 (EDIT caused by MissingUnityEvents)

Hello there,

I have been trying to learn how to use the Burst compiler but in my project, whenever Burst compilation is enabled I get 3 errors that appear to come from some code in the HDRP package.



The error text is exactly the same for all 3:

I have tried to delete the Library folder, delete both packages cache and re-install them, but to no avail.

Am I doing something wrong and how can I fix this problem?

I'm using:
Unity 2021.3.1f1
HDRP 12.1.6
Burst 1.6.6

 

I updated Unity to version 2021.3.6f1 which solved the issue

 

I was about to state that it didn't work for my actual project and that I was about to give up, but it turns out that I figured out the root cause of the problem:

My project was using MissingUnityEvents that modifies some DLL to add events to certain monobehaviour (in my case, Transform).

So, as I updated Unity to a newer version while testing Burst on a default HDRP sample project, the DLL was, at that moment, the original, and the Burst compilation started working.

Then I returned to my project and casually applied the patch like I was used to do. My project compiled, and the Burst compilation threw the same errors as before.

Reverting to the original DLL fixes the problem.
