How to reproduce:
1. Create a new HDRP project
2. Import UnityJapanOffice asset from Asset Store (Link: https://assetstore.unity.com/packages/3d/environments/unityjapanoffice-152800#content)
3. Go to Project Settings, expand Quality and select HDRP
4. Select “HDRP Medium Quality”, click Lighting > Cookies
5. Increase the “2D Atlas Size” to “Cookie Resolution 8192”
6. Open the “EveningA” Scene (Assets/UnityJapanOffice/Scenes/EveningA.unity)
7. Save the Scene (File > Save) and open it again

Expected result: Saving and reloading the Scene does not break Baked Lightmaps of the Scene
Actual result: Saving and reloading the Scene causes Baked Lightmaps to break
