Hey

This is the error that I see within your project, it seems like you’re having some trouble with particle components.

Hello, Samantga,

But in the version 4.11 it worked well and I had not errors at compilation

The engine is ever changing. It’s possible that there was some code that was changed for the newest version. I’m going to need to see whether or not you’re able to reproduce this issue in 4.12.2. It would also be extremely helpful if you had reproduction steps to recreate the critical error.

Thank you!
