No guarantees, but you can start an Online Support ticket, @Hosiaha, and see what ZOS says.
Players in this situation often have their prior guild history reviewed ... including having a guild master position (or high officer) at some point during the guild's timeline.
Be ready for questions from ZOS.
An easier alternative is to just start another guild in-game.
As posted above, you should open a ticket for assistance with your guild request. If you already have a ticket open you can post your ticket number here.
