- Is the linked storage account missing the role assignment needed from the Azure Quantum Workspace? (Instructions for adding the role assignment)
- Is the linked storage account still active? (Make sure the linked storage account wasn't accidentally deleted)
If all else fails, you can create a new workspace using Quick Create and default settings. This will create a new workspace, storage account, and create the proper role assignments:
