Moving Platter becomes unresponsive when switching from using tidal back to controller mode

I was DJing a gig and had a request for song not in my playlist. Switched to stand alone mode from controller mode using Serato pro and went into Tidal to pay a song. Executing flawlessly however after switching back to controller mode the spinning platter would not respond to manipulating the song. It would spin and I could use cue points to start the track but could not scratch as when I tried there was no response from the platter. Had to hard reboot and problem stopped. Not a good issue to have during live events. I am updated to the latest software so not sure if this may be a known issue.
