The issue is confirmed to be that the enter button automatically skips text selections and chooses the first option, regardless of whether or not that is a valid option. This can create invalid states and break the game.
So no error reports/crash logs are generated? You don't get any error message appearing when the invalid states break the game? In that case, are you using the most recent public build and what OS are you using? That could help isolate the issue if it's not possible to replicate for the dev on their own system.
