Hi Kazi Md Ikbal,
I was having the same issue and was able to find the solution.
The Microsoft.Storage resource provider was not registered in my Azure Subscription. I also registered Microsoft.StorageCache as well but it may not be required.
Once the resource was registered, the cache storage account was created without any issues.
- Navigate to your Azure Subscription
- Select "Resource Provider" from the left pane
- Locate "Microsoft.Stroage"
- Click "Register"
- Try to enable replication again.
