Don't need my LLC anymore. I will not promote

Hello there. I formed an LLC in Wyoming using Firstbase. I did this because I needed a Stripe account for my tech startup and since I'm from a third world country, I can't open a Stripe account without a US LLC. The thing is, I won't be continuing my startup for X reason. I should have waited some time before incorporating it, but it's too late to go back. I want to keep the LLC, since I spent $400 incorporating it and like the name, and will maybe use it in the future. But for now, I don't want to keep spending $35 per month (a lot of money in my country) for the Mailroom address (Firstbase feature where they give you a physical address for mailing). I reached out to them and they said this: >We have received your Mailroom cancellation request, however, before proceeding with it, **please be informed that you must have a valid US-based address to guarantee your company is in good standing. Failure to maintain an address could also result in your assets being frozen, your bank account being closed, and your company falling out of good standing with the state.** Can I cancel Mailroom still? I don't want problems with the US/Wyoming obviously, but I literally never invoiced anything to this LLC (only $1 using Stripe for testing purposes). Am I just tied to this LLC forever? I would prefer to mantain ownership. Thanks in advance! I will not promote
