Hello like szymon suggested just try to check with the admin also as you share vnet injected workspace was it done recently if yes! Then

Might be you were missing two private endpoint of  storage account you needed to create 2 private endpoints, both configured on the same subnet with one of subresource type 'blob' and one subresource type 'dfs'.s

After this if you have any ill have with connecting to it via serverless, probably needs some NCC setup in the account console.

Good luck
