error extending volume size not supported storage spaces

you can expand your volume by using powershell instead

run the following command to get the names of your StorageTiers

In my case the name is VeeamVolume

Get-VirtualDisk “VeeamVolume” | Get-StorageTier | Select FriendlyName

and then expand the desired StorageTier

Resize-StorageTier

Get-StorageTier VeeamVolume_HDD_Tier | Resize-StorageTier -Size 50TB

and after the resize

after StorageTier Resize
