Reproduction steps:
1. Open the user's attached project "Case_1263058.zip"
2. Go to Test Scene
3. Bake Lighting
4. "[PathTracer] Failed to add geometry for mesh ''; mesh contains non-finite values." Error should pop up, try to clear it

Expected result: error is cleared
Actual result: "[PathTracer] Failed to add geometry for mesh ''; mesh contains non-finite values." error can't be cleared

Reproduces on: 2019.4.23f1, 2020.2.2f1, 2021.1.0a7, 2021.2.0a9
Does not reproduce on: 2018.4.33f1, 2019.4.22f1, 2020.2.1f1, 2021.1.0a6

Notes:
-In the not reproducible streams the project crashes whenever Baking Lightning
-Error is expected, but it should be possible to clear it after canceling the Baking process
