Randomly cannot save my project. Not sure where this should go in the forums but I work mainly on structures so I figured here will do.
This is the second time I'm getting this error today and I've had work colleagues get similar errors and no one seems to know why or how to fix it?
As you can see from the image there are no background calculations running. They're also all turned off where possible. I have no idea how to get around this issue.
