Reproduction steps:
1. Open the project from the Google Drive folder
2. Make sure that 'Project Settings -> Player -> Optimize Mesh Data' is checked
3. Build Addressables using 'Window -> Asset Management -> Addressables -> Groups -> Build -> New Build -> Default Build Script'
4. Start building the project

Expected result: The project is built
Actual result: The Editor crashes after building for some time (Depending on version can take up to ~30min)
