Hi,
Unfortunately Azure Bastion Developer SKU doesn't support connecting from North Central US region to VM in East US. Virtual Network peering isn't supported by Developer SKU.
I've not seen any announcement regarding when Developer SKU will be available in more regions. Presumably when it becomes available in East US you could deploy it there so that you could connect to your VM.
Other potential options would be to connect via public IP restricted to only certain source IPs via NSG, or use higher SKU Bastion, connect via VPN Gateway, or connect via third-party SDWAN or similar.
