Anyone know if there's any older *unaffected* versions of 6000.0 URP? I think we're seeing this in 6000.0.56f1 as well.

It's crazy that this is still happening, and it was posted in the beginning of August.

Can we please get the Particle System as a package? So we can choose which package version to use, rather than relying on an entire Unity Editor version?
I've tried opening my commercial project in 6000.3.0b1 to resolve this, but the Editor gives repeating errors (unrelated to this issue), so that's not great either...

Hi @AlexM1918, for now it would be to go back to using one of the versions that do not present the problem, such as 6000.1.14f1 for example, until a new fixed version is released.

Nope, and it's still a known issue '6000.2.3f1' that just came out, I don't like that they've got this stated as fixed in this '6000.3.0b1' ...and yet not back porting it to previous versions when it is a major regression and game breaker. Can't expect people to goto a early beta, where the changes made there to URP etc probably break even more assets that aren't updated for it.
The bug reported my own experience is that I don't get these errors at all in editor.. but in a game build they appear and crash out the game after like 30seconds if particle is created...
"I get a ton of these showing in a game build with 6.2 .2f1 and seems to be caused by particle system, if no particles used or created no errors… if particle created/destroy I get these.. enough of them add up and then the game just crashes. Weirdly in editor playtests work fine and no errors seen."
Also this issue bug reporting site is ancient and terrible still don't even have a way to edit a comment :(

Did anyone find a workaround to temporarily fix this?

Is this getting fixed on 6.2 and 6lts? Fixed in 6000.3.0b1 isn't even out but it is also a beta.. this is breaking builds made in 6.2 regressions like this shouldn't happening and if they are should be back ported to fix previous versions that aren't early alpha/beta releases.
