Welcome to the Microsoft Q&A forum.
I understand the region section is unable to load in Bastion screen of the portal.
Our Product Team is aware of this issue. They also assured that they have a fix that is rolling out.
The approximate ETA for this is around 2-3 weeks.
For now, the work around is to deploy Bastion using the Preview Azure poral or deploy it from the VNet/VM blade in the regular Azure portal.
- Preview Azure portal link: https://preview.portal.azure.com/ Regular Azure portal link: https://portal.azure.com/
- Refer the below docs to deploy Bastion from the Vnet/VM blade using the regular Azure portal:
- Bastion with default settings - https://video2.skills-academy.com/en-us/azure/bastion/quickstart-host-portal#createvmset
- Bastion with manual settings - https://video2.skills-academy.com/en-us/azure/bastion/tutorial-create-host-portal#createhost
You can also use Azure PowerShell or Azure CLI to work around this.
