Crash - 11.68 - when saving activity the watch crashed (I saw a blue triangle (restarting)

I just completed a run and when saving activity the watch crashed (I saw a blue triangle (restarting))

After that when the watch was restarted the activity was not in the history (so things like trainingsstatus and hill score are not updated),

The activity was synced to garmin connect, when I looked in the activity folder on the watch (with Android File transfer) it is also their. Is their a way to process the run so my trainingsstatus etc will be updated with the run?

And the problem that the watch crashes on saving is the first time (I have used the watch for more than 3 weeks now (around the 6 activities in a week), this is first time that I had a crash) has to be solved :-)

Edit: 

I looks like that the run is in the whole history but not in the widget Last run activty (the total km's of this week is also not correct, this run hasn't be added to that), but when I open this week in the widget the activity it displays is of 2 days ago but when I press the down button I see the run of today.
