The "The assembly cannot be solved." dialog box pops up every time you fix a broken constraint. You have to accept one of the options before you can move on and fix the next constraint. (You also have to turn the sound off if you don't want to annoy your colleagues.)
In most other Inventor warning-style dialog boxes, there's a "Prompts" section which lets you suppress the message for the rest of the session - or permanently. It would be fantastic to have this option in "The Assembly cannot be solved" dialog.
I realise there are several options, so it's not always a simple yes/no answer. But if you pick "Do not show this message again this session" and then select the option you want (in my case "Accept the relationship") - the logic of the message works for the remainder of the current session. Plus, if you are choosing to suppress the dialog box, chances are you know what you're doing.
Does anyone know if there's an option for suppressing it? If not - please vote for this post on the Idea Forum (from 2017): https://forums.autodesk.com/t5/inventor-ideas/quot-the-assembly-cannot-be-solved-quot-dialog-box-pop...
(My question was prompted after spending the last two hours fixing constraints on a very old and broken model!)
