My Fenix 7 Pro Solar is crashing when using glances, version 18.11

Suddenly this week, having been on version 18.11 since it came out my watch crashes. I have tried removing from the glance, which ever glance I feel it crashes on, lets say its 10 scrolls from the bottom, ive removed that glance gone back in, and the glance that is the new 10 scrolls from the bottom then also crashes. it does the same if I scroll glances from the top it also seems to be 10 scrolls and what ever is the 10th glance from either direction it crashes.

I was asked to try this by Garmin support "

the other thing I can have you try is reinstalling the software on the watch.

Go to the menu > system > about > click the top left button 8 times > the development menu should appear > select reinstall software and let it do its thing" 

However I can't find any way of reinstalling the software from my watch as described above. 

Can anyone else offer any suggestions?
