Comment (by rollback-question):

 i found a difference between them,

 the first TBB i upgraded that doesn't recover tabs (left screenshot) is
 now on version 8.5 but based on firefox version 60.6.1esr - it shows a
 "Restart to update Tor Browser" button, when pressed the tor browser gets
 restarted but with the same version and still showing the same button
 again

 the second TBB i upgraded that recovers the tabs without problem (right
 screenshor) is on version 8.5 but based on firefox version 60.7.0esr and
 doesn't show any button and works fine

 i don't know how i ended up with this difference. i don't think i have
 messed with the first TBB during the upgrade in any way and they have the
 same settings.. one works fine the other doesn't
