Won't Fix

2020.3.X
Fixed in: 2022.2.9f1
2022.1 has reached end of life so the issue will be fixed in a newer version.
The issue occurs when we are feeding more particles than the capacity of the receiver, it relies on still experimental GPUEvent. It can be reopened in case of blocking issue.
Reproduction steps:
1. Open the user's attached project
2. Open "Firework.vfx" VFX graph
3. Increase "Rate" and "Capacity" to 99999
Expected result: Editor throws an error
Actual result: Editor glitches/freezes or Mac crashes
