Reproducible with: 2023.2.17f1, 6000.0.0b14
Could not test with: 2021.3.36f1, 2022.3.23f1 (errors)
Reproducible on: Windows 10 (if the device has 16GB of RAM)
Not reproducible on: Windows 10, Windows 11 (if the RAM is more than 16GB)

Notes:
- The exact issue could not be reproduced by CQA as the crash on our end was different
- On 2023.2.23f1 the Editor crashed with an error popup and no stack trace
- On 6000.0.0b14 the Editor crashed with a Stack Trace however, it was different from the user’s

Resolution Note:
In Unity 2023.2 peak total memory usage grows linearly with the number of probes in your scene during a bake. Of course, this is not ideal. We suspect this is what is causing this crash.
We landed a fix in Unity 6 (aka Unity 2023.3) that ensures a constant upper bound on memory usage, no matter the number of probes.
Unfortunately, we cannot backport this to Unity 2023.2. This is partially for technical reasons and partially because tech stream releases like 2023.1 and 2023.2 were never meant to receive bug fixes once they reach end of life.
We recommend that users of 2023.1 and 2023.2 upgrade to Unity 6 to get the fix for this issue.
