Looks like the thread is going to be very long without any progress. I would recommend to invest a bit of your time to create a minimal git or zip project. In many cases when doing so you can easily find an issue on yourself and if that would not be a case then you can share such sample project with community, so others may try to reproduce the problem and investigate it separately without your further responses.
The other option may be a temporary invite somebody to your private project. That would require less work from you, but obviously you would need to trust that person. I’m senior developer with many bug reports submitted from time to time in elixir, ecto, phoenix and few other projects, for example Mix test fails in umbrella (Ecto, Phoenix): db couldn't be dropped
