I had to open preferences and check on "Use legacy "File New" interface" to solve the problem
I found a fix, but it wasn't really a solution. I had backed up my Keyboard Shortcuts and Workspace and added them to 23 after install. I removed them when I was still having the issue, and it seemed to fix the problem
However, it meant that I had to totally rebuild my workspace (which consumes one screen alone) and my keyboard shortcuts. So, not a solution, but it did fix it.

Sorry for the inconvenience caused.
Does quitting and relaunching illustrator solves your problem?
If no, please email me at firstname.lastname@example.org so that we can look into the issue further.
Thanks & regards
This is happening to me now, as well. It started out as a random issue, not with every file. Now it is consistently every file I open or try to create.
