When I upgrade my HDRP project from Unity 2020.3.8f1 to 2021.2.0b2, my FrameSettings in the HDRP Global Settings are completely wiped out when I need to resolve a problem using the SafeMode. When I do the same migration but ignore the SafeMode (and solve in the full Editor), the FrameSettings are kept as they should be.

See attachment image that shows the FrameSettings with both migration (with and without SafeMode)

I also attached both Editor Log (with and without SafeMode) in case this helps.

I get this behaviour when upgrading the Reflect HDRP project: https://github.cds.internal.unity3d.com/unity/reflect.designreview.hdrp on commit 06edd811f71cfb1056da130711bc7d738a0c0dfc
