How to solve "A Native Collection has not been disposed, resulting in a memory leak." in my case?

MarTUN_Up · July 27, 2021, 3:07pm

Hello everyone,

after finally switching my project to Unity Version 2021, I often got this message in the console:

A Native Collection has not been
disposed, resulting in a memory
leak.Enable full stacktraces to get
more details.

I managed to enable that by importing com.unity.entities and now the console looks like this:

A Native Collection has not been
disposed, resulting in a memory leak.

The message appers sometimes even multiple times in the console. Unfortunatly that doesn’t help me. Can anyone tell me what to do now?

You can modify this source code to intercept that unityRequest, interrogate it, investigate possible causes and fix it on the spot.
