Description

_(Possibly the same root cause as #2026)_

Eclipse Version: **4.35.0.v20250123-1800**
OS: **Windows**

After a restart, the UI froze for a few seconds. The culprit seems to be the package explorer since no "special" action was triggered by the user (just clicking in the code editor).

Here is the sample: [snapshot-1739195911281.zip](https://github.com/user-attachments/files/18826085/outline.snapshot-1739195911281.zip)

Research direction

Start by inspecting the attached performance snapshot and reproducing the freeze on Eclipse 4.35.0.v20250123-1800 on Windows after a restart, then compare the symptoms with issue #2026. Trace whether Package Explorer is responsible for the pause; done means the cause is identified and the post-restart UI freeze is addressed and verified.
