Cannot Make Artboard #6 in a multiple artboard file

[Devin Trier]

Someone please help me out here with a problem I've NEVER encountered before.

I can no longer make Artboard #6 in any new AI file. Doesn't matter if I create 10 boards from the New Document window, or if I click/copy/drag from one artboard to make multiple - Artboard #6 does NOT appear. Never! I can't even explain how weird this is, as I've never encountered this problem before. Any insights from the community here?

No issues for me on version 27.8.1

What version are you using?

[Devin Trier]

Same! It's wild.
