There is a fundamental design problem of the "manager" and the "wait group".
If nothing has started, the "Wait" just panics: sync: WaitGroup is reused before previous Wait has returned
There is no clear solution besides a complete rewriting of the "manager"
If there are some mistakes in the app.ini, end users would just see the "panic", but not the real error messages. A real case: #27643
This PR is just a quick fix for the annoying panic problem.
