Not able to remove fileshare with backup enabled via terraform in one region only

Question

I have two recovery service vaults in two different regions, south east asia and west europe.

But I only get this error message when using terraform to destroy the azure fileshare that has snapshot inside for SEA only. I did the same testing for fileshare in west europe, no error at all.

deleting File Share "seashare" (Account "Account \"myseafileshare\" (IsEdgeZone false / ZoneName \"\" / Subdomain Type \"file\" / DomainSuffix \"core.windows.net\")"): executing request: unexpected status 

Both using the same azurerm provider 3.116.0 and I created both RSV using same terraform configuration except location. Both RSV have the soft delete enabled on these properties : Enable soft delete for cloud workloads, Enable soft delete and security settings for hybrid workloads.

I am able to terraform destroy the seashare after I turn off the Enable soft delete for cloud workloads, Enable soft delete and security settings for hybrid workloads and manually delete the snapshot for the seashare.

I checked the lease on the file as well. REST file lease: State -> Available , Lock -> Unlocked

Any idea on why the behaviour could be different when they are having same RSV setting / azure fileshare setting except location?
