1.12.1 Software freezes using crafting table & during two player teleportation.

Actually version 1.12.1 but cannot enter this in versions above. Have minecraft pre-installed on console. Purchased & used since Christmas 2018. From May 2019 will play for approx 15 mins without fault. Then on opening chests or using crafting tables software freezes & has to be re-booted. When playing two player have the same issue when trying to teleport to each other. Are there software updates we have missed? If so, where do we find them as console states none available. Thank you 6
