[Mac] Video-heavy project does not get successfully imported when launching the project in batchmode



How to reproduce:
1. Download and extract the linked project
2. Launch it from the terminal using "<UNITY_PATH> -quit -batchmode -projectPath <PROJECT_FOLDER_PATH>"
3. Inspect the Editor.log

Expected results: The assets get imported successfully with no errors
Actual results: After about 40 videos are imported, all the following ones print a "Cannot Open" error to the Editor.log

Reproducible with: 2017.4.32f1, 2018.4.9f1, 2019.2.6f1, 2019.3.0b3, 2020.1.0a4

The full error:
Error Domain=AVFoundationErrorDomain Code=-11829 "Cannot Open" UserInfo={NSLocalizedFailureReason=This media may be damaged., NSLocalizedDescription=Cannot Open, NSUnderlyingError=0x7feb29f06390 {Error Domain=NSOSStatusErrorDomain Code=-12137 "(null)"}}
(Filename: /Users/builduser/buildslave/unity/build/Editor/Src/Video/Media/AVFoundation/ Line: 1060)

  1. Resolution Note (fix version 2020.2):

    Delayed cleanup after importing videos does not get executed early enough when running in batch mode. Changing the execution vehicle for the asynchronous work in this situation will cause the cleanup to happen earlier.

    Fixed in 2020.2.0a1.26

    For what it's worth, we have further determined that this issue does not occur either when -batchmode is disabled; as in: running the build with the GUI enabled.

    This is definitely undesired for our build server (and isn't possible on Cloud Build), so any progress on this would be greatly appreciated.
