Logged in, but unable to access designer

I am having this issue as @ByThePeople, one year later (Feb 24 2022). I am trying to access my clients website on their new webflow account, using their login. I can make it to the dashboard, editor and project setting but not designer!

Does anyone know what is causing this and whether I can do anything about it?
