Reproduction steps:
1. Open "1172486" project
2. After Script and Assembly Definition reloading is done, close Unity
3. Edit the "BuildServer.bat" file
3.1. Change the Unity path appropriately
3.2. Delete "-SERVER TRUE"
4. Run the "BuildServer.bat" file
5. Run the first build in the newly created "Exports" folder
6. Run the second build

Actual Result: The Second build crashes

Reproduced with: 2019.2.1f1, 2019.1.14f1, 2018.4.6f1
Couldn't reproduce with: 2019.3.0a11 (Only one build finishes with the batch file), 2019.3.0a1 (Project breaks), 2017.4.31f1 (Project breaks)

Note:
The first build doesn't seem to work properly either (seems like a silent crash), but doesn't crash with the "Crash" pop-up
Ignore any custom pop-ups that appear when loading the project
