Watch crashed/showed blue triangle while saving an activity

After installing the new watch update this morning, I went on a long run, saved the activity, and as it was saving, the blue triangle appeared and wouldn't leave. I held the power off button and it just showed a screen saying "content expired" message then it takes me back to the watch face. I had started the activity as a trail run, but the activity logo are what look like 3 olympic rings (?multisport). The activity doesn't show on the watch as an activity as part of my training plan, but does show as an activity in general. It's not syncing to garmin connect. Not able to find the file on my mac when i sync the watch to garmin express. 

Anyone else have this problem after today's update? Seems like it's part of the notorious garmin bug that was happening before, just never experienced it before this. 

Really want this activity to upload/sync, was my longest run yet.
