Bug Windows: Native Crash in igd10iumd64 affecting Intel Integrated GPU users

    I'm getting a large volume of "Native Crash - KiUserExceptionDispatcher" reports. I've included a subset of them in the link below as well as what GPU the user was using. In all the logs, the crashes appear within the igd10iumd64.dll, but I'm unable to see what the error message is and I'm not sure where to find the pdb to upload to Unity Analytics to enable those logs.

    I'm using 2021.3.8f1. The issue was occurring on 2020.3.12f1 and 2020.3.38f1.
    The project uses URP with almost all Shaders written with Shader Graph, and 98% of VFX done through VFX graph, with about 3 bullet projectiles using Shuriken. Our game is a Tower Defence, and the crashes seem to consistently appear in the later waves where the players have more on screen. I've not seen any pattern yet with any specific unit or spell triggering the crash. Quite a lot of our VFX use the Particle Strip node which has caused me to believe this might be our issue:

    The link above and from what I can see within those linked stack traces make me believe this is within VFX Graph. If it's not, let me know what area is causing the crash and I will post in those forums instead. Any advice as to how I can further track this down would be appreciated. I don't have access to the hardware and I'm unable to replicate the problem on my side.
