I create a copy of a survival mode and set it creative mode to test some build. However, it turned the original (survival world) into creative mode as well, even though the setting is still in survival mode. There were no problems before the update, I made copy of the survival world multiple time, set all the copy worlds to survival to test builds, and my original world was not affected. However, this time my survival world got stuck in creative and I can't mine any blocks, even when change from creative back to survival.
