What did you do to my canvas?

[#1]

I open Adobe CC and I have nothing but grey - I have to load all toolbars and all the windows every single time, okay I will take a break until you get this fixed. I have no workspaces. Now my toolbars go where ever they please. Isolation mode on every other click. I really hope you get this fixed soon. I can't tell you about any of the new features because it keeps crashing and I can't get any work done. Thank you.

Did you rebuild the preferences after updating (or while doing it)?

You might want to try it by renaming the folder https://helpx.adobe.com/illustrator/using/setting-preferences.html

If that doesn't help, please show screenshots.

Please tell us your system.
