I got the error message saying that "Adams has stopped working and exported. This is a fault of the software, not your model................". The model is pretty big (model of motorcycles ) in which there are chassis and swingarm and an ac synchronous motor as well. If I make this very model small by removing the motor and swingarm, then error won't come but in the full model.
The cause of your problem will be probably something else then win version. But i have noticed on several comuters that windows update win10 20h2 was causing issues. Now i am strictly using following link about win version.
