Hello @peter_hoeltschi !

I think your workspace or user permissions only allow SQL/serverless compute not classi clusters because even if you have enterprise pay-as-you-go at the account level does not automatically mean every user can create all-purpose compute in every workspace.

Ask a workspace admin to check that you have workspace and allow unrestricted cluster creation is checked or at least access to a compute policy such as personal compute

Databricks docs say this entitlement controls whether a user can provision unrestricted compute, and without it users can only create compute through assigned policies. https://docs.databricks.com/aws/en/security/auth/entitlements
