The windows from the previous session are not being restored correctly

Does this issue occur when all extensions are disabled?: Yes/No

- VS Code Version: 1.135.0
- OS Version: Ubuntu 24.04/26.04

Steps to Reproduce:

1. Open a folder or workspace in a multi-window setup.
2. Close VS Code.
3. Now reopen VS Code.
4. Only the editors from the main window are displayed, and no other windows are opened, even though the files are separated into different windows in the Explorer sidebar.

⚠️ To restore the previous state, you have to close VS Code and reopen it again so that the windows are restored correctly.
