How to reproduce:
1. Open the attached project from the Google Drive
2. Make sure the Editor is using Vulkan Graphics API
3. Open "AVP6_Desktop" Scene
4. Open Lighting window (Windows > Rendering > Lighting)
5. In the Lighting window make sure the Lightmapper is set to "Progressive GPU (Preview)"
6. Click "Clear Baked Data" found in the "Generate Lighting" drop-down
7. Open the Preferences window (Edit > Preferences)
8. In the Preferences window click on "Clean Cache" found in the "GI Cache" category
9. Click "Generate Lighting" in the Lighting window
10. Once Lighting finishes generating repeat everything from the 6th step

Expected result: Editor successfully generates lighting
Actual result: Editor crashes

Reproducible with 2020.3.16f1, 2021.1.19f1, 2021.2.0b9, 2022.1.0a6
Could not test with: 2019.4.30f1 (Lightmapper falls back to Progressive CPU)

Notes:
- Reproducible with NVIDIA GeForce GTX 1060 6GB
- The Lighting Settings asset is called "AVP6_DesktopSettings"
- It should crash on the second attempt to Generate Lighting, but it may take more attempts depending on the GPU VRAM.
