How to reproduce:
1. Open the attached “IN-143424” project
2. Open the “APV” scene
3. Open the Lighting window and open the Adaptive Probe Volume tab
4. Enable then disable “Dilation” in the Probe Invalidity Settings
5. Click the arrow on the right side of the “Generate Lighting Button”
6. Click “Clear Baking Data” then “Bake Probe Volumes“
7. Once baking has finished, click “Bake Reflection Probes“
8. Observe the crash

Reproducible with: 6000.0.17f1, 6000.0.76f1, 6000.3.17f1, 6000.4.10f1, 6000.5.0b12, 6000.6.0a6
Could not test with: 6000.0.16f1 (Lighting Data become corrupted when downgraded)

Reproduced on: Windows 10 (user reported), Windows 11
Not reproduced on: No other environment tested

Notes:

If the crash does not occur the first time, repeat step 6 two or three more times
Sometimes, the issue reproduces more consistently if the Directional Light GameObject is active (Lights > Directional Light)
It is not necessary to clear the baking data (step 6) but the issue reproduces more consistently when this is done
Could not reproduce the issue on a fresh project
