I've started to see this happen occasionally in 2018.09, but I cannot reproduce it in 2018.08 or earlier.
It happens mostly when pressing play the first time a project loads, or occasionally when rewinding and playing from the beginning (i.e. pressing W followed by spacebar).
In both cases, the song starts playing normally but refuses to stop. It ignores both the spacebar, and the stop button on my Korg NanoKontrol Studio (if this is connected).
The only way I can get Cakewalk to stop playing (short of resorting to task manager), is to switch off my Scarlett 6i6.
Cakewalk then picks up the fact that this has gone and stops with an audio dropout error. I can then switch it back on, wait until Cakewalk recognises it, and then continue as normal.
The weird thing is certain things, like Ctrl + S to save the project, actually work when it's doing its non-stop playing thing. So it's not completely unresponsive.
I've not managed to find a pattern to this. Project size or complexity has no bearing on it - it's happened on the simplest of projects (e.g. one Instrument track with AIR Mini Grand).
[Edit] - Just happen again yesterday evening, however this time it just played a long buzzing sound.
