The Problem:

When running a Unity 2D project, an error message appears: ‘Leak Detected: Persistent allocates 2 individual allocations.’ After enabling full stack traces in the project settings, a verbose output is generated, but the user is unsure how to interpret it to identify the cause of the leak.

The Solutions:

Solution 1: The error you’re encountering is a known Unity bug in the 2023 version.

Without the code or reproduction steps, it’s difficult to determine the specific cause. It’s recommended to update to the latest version of Unity (2023.2.xay or 2023.1.xby) or switch to Unity 2022 and check if the issue persists. If so, report the bug using "Help -> Report a bug" and provide reproduction steps and the call stack. Unity’s support team is responsive and will assist with bug resolution. Remember to clean up personal information before sharing logs publicly.
