Watch freezes using Trackback

Anybody else having issues with Trackback?..or is it working for you? 

I use walk activity, walk for about a mile, stop, then choose trackback, then route.... the watch instantly gives me the route back then freezes, I have to hard reset by holding the light button, then I have to stop navigation when it's loaded again....I have used trackback successfully today, but for some reason in this one location the watch will freeze, I'll keep testing different locations. 

Just seeing if this is a bug, maybe a weird location, or a mistake on the OSM based map?,.. or I'll send my Fenix back to Garmin for a replacement after testing some more. 

I'm on 8.39 using Talkytoaster, Fenix 7x solor Sapphire one week old. 

Thanks...

Ps.. See pics of map disappearing after trackback is selected using route.... 

And music widget in the activity froze and not central... Only a hard reset will solve.
