[IGN-12611] Basic session properties gone 8.1.47

I recently upgraded to version 8.1.47 and now the session properties don't show not even the basic restricted ones (host, theme, lastActivity, etc...), anybody else experiencing this issue?

I tried to close/open the designer a few times but still nothing?

I noticed this because out of nowhere my theme colored changed to light and the only way I could interact with session props was through a component prop binding.

Okay this is a mac issue I'm encountering, I opened a designer in a windows VM and the session props appeared and I was able to set back my original sessions properties and then had to kill my old session from the gateway page to see the updated changes.

I get the following error only when I try to update and save on mac obviously because the session props don't exist. In windows everything works.

Do you show any errors in Console on initial launch of the Designer?

This is the only standout information I get from the output console on startup but its all level INFO

Okay, we're tracking this one under IGN-12611. One workaround that I've found to help is to use File->Open after you've opened Designer and re-open the same project.

haha that's a very interesting work around, that worked I can update, save, and see the session props on my mac again with no error.

How did you figured that out?

Seeing that something went wrong in the DesignerHook, I had a whim to see whether it would reproduce on in-designer project openings. Thankfully it presented itself accordingly as a workaround. We've still got a deeper analysis on this one pending internally--it seems to be just macOS, as you helped confirm further.

Any update on IGN-12611, I started running in to this same Unable to save session props error and re-opening the project while the designer was already open, fixed that specific issue. In addition to that my designer just disconnects for ~100ms or so and then reconnects, not sure if this is related to this same bug, this disconnect loop happens every minute or so.
