Unreal Engine Issues and Bug Tracker (UE-73016)

Description

Attached Project:
[Link Removed]

Since Upgrading project to 4.22, Licensee has been experiencing an Assertion crash in their built game.

"I'm not exactly sure why it crashes. It's a very specific combination of things: Writing a material to a render target, and the lit steam effect from the starter content being a certain distance away."

From the investigation it seems to be related to the Tick group Cascade particle system submission.

Regression?: No

Licensee reported that this was a regression from 4.21 but as we were only able to reproduce with their provided 4.22 project, we were unable to confirm.

Steps to Reproduce

Download the attached project: CrashRepro422-Build.zip
Open the project and package the project for Windows 64 Build.
Run the CrashRepro422 Application

Result:
Assertion Crash: Assertion Failed: !bPostTickComponentUpdate File\Engine\Source\Runtime\Engine\Private\LevelTick.cpp] [Line:885]

Expected:
Package Game starts properly
