Hello @StevenMINDD , Thanks for using Microsoft Q&A Platform.
There is a limit of only one allowed 'Free' account, per resource type, per subscription.
The issue could be due to an existing Free tier resource that has already been created in that particular resource region.
The workarounds would be trying different region or deleting the existing one and choosing different region or upgrading the Free pricing tier to standard tier if quota is utilized. Please always choose the best that fits with your subscription limits and needs.
I hope this helps.
Regards,
Vasavi
