Yes, all commissions are closed at this time. Yes, including professional/commercial/personal projects.
No, I don't have an idea of when they will be open again.
As stated above, commissions of all kinds are closed and there is currently no plans to open them again. If you send a message inquiring about commissioned work, an original map based off of your designs, a map for your project/novel/show/whatever, doing a project with you, collaborating on a map with you, or any other type of work-for-hire/project, I'm sorry to say that I will not respond.
