heres the error:

after that this:

XRSystem.ReleaseFrame() was not called!

removing the light in the blastparticle fixed the problem

I am having this issue as well, but I am hoping there is a solution that doesn’t require removing the light, as the light is rather important in my instance. I have a pointlight attached to a collission effect, but when it spawns I am getting the same error as listed in the original post.

It is fine and works well just hitting play in Timeline while editing, but once you actually play the game and it runs, is when it has the issue.

Ok, so it looks like this only happens (for me anyways) if you have a particle system in which is using the Lights functionality to try and call a pointlight. I just instead moved the pointlight to use an activation track from Timeline instead of letting the particle system do it, and I no longer have an issue.

As far as I know this issue was fixed in HDRP 7.1.3

How do i upgrade to that version?? i am currently using 6.9.1 and dont get the option to upgrade?

7.x is available only in Unity 2019.3x
