Terraform Error: Provider configuration not present means state still associates one or more managed resource instances with a provider configuration address that the current root module can no longer supply. The missing object may be a deleted child-module provider block, a removed alias, an absent module call, or a changed provider source. Repair the execution context before planning any infrastructure change.

Terraform Error acquiring the state lock means the configured backend refused a potentially state-writing operation because another lock exists or the lock service is unavailable. The safe response is to identify the exact backend, workspace, lock owner, and active run before considering force-unlock.
