If your game crashes during the continuation of a previous save...
Just opt into the low-end build. Sometimes whenever something new is added into the game, it runs the risk of crashing someone's game. It's mainly only for players who are continuing from a previous save. But, people starting from a new game are pretty much free of this problem. The quest-logs are a thing that are almost guaranteed to cause this issue for players continuing from a previous save.
The low-end build is best for players continuing the game from a previous save. Especially if you lag hard from the pre-battle transitions. Again, upon a new game. You should be just fine.
This is the testing phase after all, there are going to be issues!
