Reproduction steps:
1. Open the attached project "Project.zip"
2. Open the Task Manager
3. In the top left menu under "Tools > Bolt", run AOT pre-build
4. Observe the increase in System Memory usage when running the AOT pre-build

Expected result: System Memory usage does not increase significantly when running Bolt AOT pre-build
Actual result: System Memory usage increases significantly when running Bolt AOT pre-build

Reproduces on: Bolt 1.4.13 (2019.4.18f1, 2020.2.3f1)
Could not test on 2018.4.31f1 due to the project breaking when downgrading
Could not test on Bolt 1.5.1-pre.3 (2021.1.0b3, 2021.2.0a3) due to the context menu where AOT Pre-Build is located not appearing

Notes:
-User reported that on a 64GB system running AOT pre-build uses up approximately 55GB of system memory
-Issue does not reproduce on a new project
-On a 32GB system, AOT pre-build used 12GB of system memory
