Starting the Eclipse IDE works normally and does not freeze the UI.
Current Behavior
Starting the Eclipse IDE, the UI freezes for several minutes because of org.eclipse.buildship.core.internal.preferences.DefaultModelPersistence.loadModel(DefaultModelPersistence.java:70) blocking the UI thread.
Context
This happens since upgrading to Eclipse 2023-09 (Build id: 20230907-1323)
Steps to Reproduce
Your Environment
Here is a thread dump of the UI thread.

Expected Behavior
Starting the Eclipse IDE works normally and does not freeze the UI.
Current Behavior
Starting the Eclipse IDE, the UI freezes for several minutes because of
org.eclipse.buildship.core.internal.preferences.DefaultModelPersistence.loadModel(DefaultModelPersistence.java:70)
blocking the UI thread.Context
This happens since upgrading to Eclipse 2023-09 (Build id: 20230907-1323)
Steps to Reproduce
Your Environment
Here is a thread dump of the UI thread.
