In my Solution is only one project (which is larger due to composer files etc.).
I do not have changed any configuration regarding "Publish", so to be honest I don't know the default settings there.
We use the TFS as code repository but this is something I have to trigger if I'd like to commit code to Azure. So I guess there shouldn't be any other publishing.
I do can type during this 5 secons but the editor freezes completely and after the "delay" my input becomes visible (sometimes you can see that it will be added character by character).
I will create a screen record of the issue.
