Sorry about the issue, that's very unfortunate! Based on the error code, it does indeed seem like something went wrong when your computer lost power, probably related to some files not being saved properly. As such, it most likely isn't something we can fix in an update. That being said, we suggest that you try the following:

1. Locate your savefiles in your computer's folders by going to: user->AppData->Local->Mistwinter Bay. You need to allow to show hidden files, or the AppData-folder and all folders in it won't show up

2. Delete the "settings.save" file. Start the game and see if it starts like it should. Deleting this file means that you have to re-apply any custom settings

3. If the above step didn't work, repeat the process but delete the "menus.save" file instead. Deleting this file means that menus, such as the Townsfolk Roster etc, opens in a default setting and not where you last left off

4. If the above steps didn't work, repeat the process but delete the "savemanager.save" file instead. It's worth noting that when this file is deleted, your savefiles will not be properly displayed when saving/loading in the game, but they are still there and can be loaded and saved to as before. Deleting this file will also delete some achievement progress statistics, achievement coins and some other things. As such, for the best experience, it might be worth it to delete the "achievements.save" file as well so that all achievements can be obtained again

5. If none of the above steps worked, deleting all remaining files should hopefully solve the issue. Unfortunately, this means losing all current saved games

We hope one of the steps helps!
