Unable to subscribe workspace to Starter plan after unregistering and registering again

Description

Title: Unable to subscribe workspace to Starter plan after unregistering and registering again
Hello,
I’m using Rocket.Chat 8.4.1 (self-managed).
My workspace was previously on the Starter plan. I unregistered it from Rocket.Chat Cloud, registered it again, and Starter was assigned successfully.
Later, I unregistered it again. Now, after registering it once more, every attempt to activate the Starter plan fails.
Cloud shows my workspace as Community Edition, and when I click Subscribe to Starter, I receive:

“We were unable to subscribe your workspace to the Starter plan.”
Request ID:
3978afeb-0376-4bf8-8ae3-92e32bdecea2
My server logs also show:

App could not be enabled
appName: WhatsApp Cloud
message: invalid-license

and

Error getting the App from the Marketplace
error: purchased required

Workspace ID:
6a4c4087d7e32f49f18b8140
Could someone from the Rocket.Chat team verify why this workspace can no longer be subscribed to the Starter plan?
Thank you.
