PT 12.3 quits when commiting multiple Instrument Tracks

I was experimenting with track commit. I wanted to take 5 instrument tracks, each with a different VI, each playing its own part. I select the 5 tracks, (like shown in the video) and tried to do the track commit. It began rendering and then PT just closed and didn't reboot. That seemed rather strange. I had done a multi track drum part with Transfuser earlier with no issues.

Anyone else had an issue trying to use TC on multiple instrument tracks all at once?
