How to reproduce:
1. Extract the “lights-memory-tests.zip“ project
2. Install Python on the computer (the reporter specified Python 3.13)
3. Open the Command Prompt as an administrator
4. Install two extensions by running “py -m pip install pillow pywin32“ command, in the Command Prompt window
5. Within the project directory, open the “project_config.json” file and change the “unity_version“ and “unity_exe“ values to the version to be tested
6. Save the changes
7. Run “[full path to the project]\run_project.bat -t build,split” command, in the Command Prompt window
7. Wait until the build and tests finish (might take 10+ minutes)
8. Observe the Yellow text in the Command Prompt window

Expected result: The memory difference is noticeable (<15MB)
Actual result: The memory difference is significant (>40MB)
