I don't know what would cause this. But you can try using TCC instead.
The reason why the crystal spins with the wrong speed is because of a bug that I fixed after I made the snapshots. I can hear the weird sounds too,...
This will never happen.
Try again with master and reopen if still not working.
I think they have done so many .asm patches that it's too hard.
Fixed in aefcb08
