Same here. Using 2020.2.7f1. Have 2 scenes. 1: Loading scene to connect to Photon, and Game Scene where all game play takes place, which is a rather large scene, and I noticed, when trying to Generate Lighting, it just seems to go on forever, but did see a size of 2GB, so I switched over to Auto, and reduced the resolution from 1024, to 256, and apparently, this is still to large, SO, am having to delete my TEMP and LIBRARY folders (3,452,886 items and 3.96Gb of data), and will see if I can load my project after that. Perhaps need to limit the size of my Game Scene, and break it up into different scenes.

Same. Using 2019.4.3f1.
It bakes a 2.1GB file out in any resolution. That 0.1GB is really driving me nuts. -

Anything over 2gb causes this issue. Can not assign lighting data to scene.

Me too... did a big light bake in 2018.2.20f1, it made a 3.1gb lightingdata.asset and now it won't load Unity.

Resolution Note (2021.2.X):
The file serialization system needs 64bits support, until that happens, please split the scene into smaller chunks to avoid exceeding the maximum 2GB size.
