Having the same issue here, out of the 7 flights I did I only managed to land twice (those two were very short flights maybe thats why??).
For the other flights some or all of the displays/FMS froze near the TOD or during the descent. Once it happened while selecting the approach after a long haul fight, once while selecting BTV or while doing the approach checklist. So all of them during high workload scenarios for the sim I guess.
Quite frustrating having the sim freeze after a 6 hours flight and shortly before landing especially as this is no freeware aircraft but an 80 euros Product 😞
