I would like to know more about this issue. Tell me about your develop/build environment.

• UIParticle 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 attach a minimal project (included Assets, Packages and ProjectSettings directories) that reproduces the issue?
