Hello! That’s an error I’ve never seen or encountered before but I’ll try my best to help.
For trying to upgrade or downgrading the URP package, find URP under the Unity Registry and click on the triangle button next to it open the drop down menu. You should be able to see the different versions if you click on “See All Versions” then from there you can try a different version of URP
As for the errors themselves, I tried looking it up and the problem may be related to the Burst package, which may be a dependency for URP. Could you help me check what versions of Unity, URP and Blitz you’re using?
Hmm, According to that thread I linked, I believe thats the correct version of Burst to use as a dependency for URP.
Could you try installing URP in an earlier version of Unity like 2020, and see if you encounter the same error? Maybe the issue has something to do with that specific version, as my project using URP in Unity 2019 (i don’t remember the exact version) doesn’t face this issue.
