Based on what you've described the failure is the copy process that's used to 'duplicate' annotation placed on sheets to the new duplicate sheet (Detail lines, text, dimensions, symbols etc). So there is either something wrong with the annotation items being copied, or with the destination sheet they are being copied to.
That gives you a line of enquiry to determine which sheets have this problem. Do any of the sheets successfully duplicate? If so, check where it stops (you need to check the sheet list input in Dynamo) as the next sheet in the sequence is the sheet that has the problem. Once identified, try duplicating this sheet in isolation. If the problem triggers, save it to a new file with annotations + views and upload it so I can debug it.
Also, please ensure you are running BimorphNodes v2.0.4.
