Go to General and About in settings. See how much space you have free. Every new major update I’ve had to reset and restore from backup (I think logs eat up the space) then it works.
2.7 GB free.
Then you don’t need to free up that much space. If there are any apps you never use, try uninstalling them. Maybe try @slooksterPSV’s suggestion about resetting and restoring from backup.
