Thanks for the report!
Tell me about your develop/build environment.

• Package version [e.g. 3.3.10]
• Platform: [e.g. Editor(Windows/Mac), Standalone(Windows/Mac), iOS, Android, WebGL]
• Unity version: [e.g. 2022.2.0f1]
• Build options: [e.g. IL2CPP, .Net 4.x, URP/HDRP]

Could you please provide a minimal reproduction project that includes the Assets, Packages, and ProjectSettings directories?
This would really help us investigate and resolve the issue.

No need to include any proprietary assets from your project - feel free to use placeholder or free assets instead.

This bug occurs sporadically.

For example, is there any additional information, such as “this occurred when I instantiated a prefab from code” or “this occurred when I scrolled”?
That would help us pinpoint the issue. :)
