You cannot run flows that have errors in them. Even if the sub-flow is never called, if it has an error, it will prevent the entire flow from being compiled. You need to either fix the errors, or disable/delete the actions that cause the error. When you do that, you will be able to run your flow.
See the errors and warnings on the bottom of the designer window to find all errors and fix them.
