Hello Spencer! Thank you for bringing this to our attention! I don't see that we have this behavior logged as a bug, but it sounds like something I'd like to report to our team. I have tried to recreate this issue on my end, but I do not see the Save icon greyed out at all. I've selected it when opening a new project that hasn't been saved, closing and reopening a project that I've already saved, and while working on a project that I've already saved multiple times before. I have tested this behavior in the latest update, 3.91.33139.0.
It would be helpful to include a screen recording of this issue in my report. Would you be willing to record your screen as this behavior occurs?
