Norton settings not opening

Hi, this week I found out that sometimes when I click settings in the norton360 app(not my norton) the setting windows won't open, but if I do a restart everything is fine again, then after sometime the setting won't open again. Anyone know why? 

re: W10 Fast Startup Off....maybe, M$ Tuesday updates reset W10 Fast Startup On? 

other than run Norton LiveUpdate several times + machine Restart.  Repeat. 
-- maybe, refresh Norton install 
-- following along with interest
