Can anyone tell why this graphic anomaly is happening?

Platform: Android Vulkan
Version : 4.27
Blueprint project

Every time I get hit by a red projectile I spawn a Niagara system. The system spawns fine but there is this black blob around it as shown in the image.

The black blob does not appear in editor and also does not appear when I launch the project via USB on phone. It only appears on Android packaged game.

It does not appear in IOS either so it’s an Android issue.

Anyone been through this problem before?
