Repro:
01) Download attached repro project AutoBake_HDRPIssue.zip
02) Open using the above editor version.
03) Open the Scene Lightprobes.unity
04) Auto mode is enabled in the Lighting Settings window. Allow this to complete.
05) Observe the lighting is baked correctly.
06) Save the Scene and close the Editor.
07) Reopen the same project.
08) Allow the Auto bake to complete again.

Observe:
After the Editor is closed and repoened, lightmaps will now appear black. Rebakes do not fix the issue. The Scene will feature permanently black lightmaps. On Play, the lighting will look as expected, but in Edit mode, baked lighting is toast.

When the project is converted to Legacy RP, this problem does not repro.

Expected:
Precomputed lighting should rebake consistently. Completed Lightmaps should be visible during Play and Edit mode.
