[Addressables] Unity runs out of memory when building Adressables, the build is never completed

Package: Build Pipeline - Addressables


Reproduction steps:
1. Extract the project in""
2. Execute 'xattr -cr case_1332957-InstallationTracker' in the location you extracted the project
3. Open the project
4. Go Window -> Asset Management -> Addressables -> Groups
5. In Addressables Groups window click Build -> New Build -> Default Build Script

Expected result: A progress bar will show up and after a while the build completes
Actual result: A progress bar shows up, the build never completes, In about a minute of building time, Unity will take up all available RAM on the device and will stay in that state indefinitely

Reproducible with: 1.4.0 (2020.3.6f1), 1.18.2 (2019.4.26f1, 2020.3.7f1, 2021.1.6f1), 1.17.17 (2021.2.0a15)
Could not test with 2018.4.34f1 (package errors, project breaks)

Reproducible on Windows and Mac

1. The customer mentioned that this sometimes causes the entire computer to crash/ shut down, but I was not able to reproduce this behaviour. The RAM fills out but nothing happens afterward.
2. Force Quit the application at any point to free the RAM

    We are completely unable to build our game for Windows on a machine with 64gb or RAM.
