C8 unresponsive - initializing 15% updating database

@bobbyD I am having the same issue reported by @johnny2678 on my c-7 hub. After soft reset, it is stuck in the Initializing Hub: 15% state. As a result, I never get to the screen to restore the database. I've also done the network reset with no help along with all the steps recommended by @jtp10181 . My hub has been problematic for several weeks requring frequent shutdowns to restore the zwave radio. In the past couple weeks, I started experiencing frequent corrupt database issues so have done many soft resets without issue. But now I cant get past this screen. I bought a c8 pro hub and wish to migrate to it from c7 but am stuck. With over 150 devices and many complex rules, i really dont want to start from scratch
