Unity Issue Tracker - Projects are not opening due to an Infinite Loop when a Script with the OnPreprocessAsset() Function from the Documentation is present

2023.3.X

2023.2.X

2023.1.X

2022.3.X

Issue stems from faulty code in the documentation, it was updated with the code that does not have the issue.

How to reproduce:
1. Open the user-attached “AddressablesShaders.zip” Project

Expected result: The Project opens
Actual result: The Unity Editor becomes unresponsive and the Project doesn’t open

Reproducible with: 2022.2.0a3, 2022.3.6f1, 2023.1.6f1, 2023.2.0b2
Not reproducible with: 2021.3.29f1, 2022.2.0a2

Reproduced on: macOS Ventura 13.4 (Intel)

Notes:

Issue is not reproducible when the Project has Compilation Errors
The Function causes an Infinity Loop in the Script Compilation process
“OnPreprocessAsset()” Function is taken from this documentation: https://docs.unity3d.com/2022.3/Documentation/Manual/DefaultPresetsByFolder.html
Workaround is to not process folders in the Function
If the issue no longer reproduces on the Reproducible versions, delete the Library folder
