Hello gibsonjsh,
I am sorry for this very late note. My apologies. It seems that it has slipped through the cracks! Thank you for sending it to us along with crash log! I'm sure the team in charge had taken it all into account.

I hope that this problem did not last too long for you and that one of the many updates to the product was able to fix everything.
Feel free to start a new conversation with our community of experts if need be.
Yours sincerely,
Gwen
