Loud BANG then...

Something could have gone wrong during the engine mount change. Don't they have to drop the engine a few inches? The other possibility is the clutch disc.

Doubtful. The engine has to move a tiny bit, unless someone has no idea what they are doing. It’s a straight forward job.

Regarding the IMS, if you are taking out the tranny for some reason do it, as well as the clutch, and RMS. The primary labor is simply accessing these things. I think the IMS thing is real, but hyped for sure. But, if I were ever needing to have the tranny removed, it would get done.

I vote axle as well. Not sure what was meant by “one axle drives another etc” odd...

BTW, if an axle it’s very easy to diagnose. Like get it up in the air and look...

I suspect what he was talking about was the open differential. For those who may not understand that, in an open differential, if one wheel is in the air, it will Spin and spin and spin and the other wheel will not turn.
Likewise, if one axle is broken, the shaft will Spin and spin and spin and no power will be applied to the other wheel. In other words, breaking one axle is as good as breaking both axles! :-) haha

Given the bang, and then the lack of any other noises afterwards, I would also vote for the axle. There are things that could go on in the clutch, or in the transmission itself, which could cause the symptoms you are experiencing, but you would most certainly hear things rattling around now.

And as has also already been said, you should be able to diagnose that very quickly, just by peering underneath the car.

+ one more vote for an axle/cv joint that failed..

Thanks for the comments guys. I'll hear from them tomorrow. I agree with maytag and Gilles, but hope it's not too major.
The previous owner recently had the clutch and pilot bearing replaced.

Yeah, he could have been talking about the diff... just an odd description if so. But I suppose in “lay” terms it would make sense to describe it like that.

Doubtful it’s the motor mount...
