Shoot. Sorry that you're having this issue. The beta has a change which limits the minimum resolution that can be set to help avoid this problem, but it doesn't work retroactively. It only keeps players from scaling too low. For now, you'll need to reset the registries where Unity saves resolution screen sizes.

If you are on Windows:
1. Click the start button.
2. Type 'regedit' without quotes.
3. Navigate to HKEY_CURRENT_USER > Software > Unknown Origin Games > Odd Realm
4. Right-click Screenmanager Resolution Height, select delete
5. Right-click Screenmanager Resolution Width, select delete

You should be able to open the game and it will pick the appropriate default window size for your monitor. If not, you might need to specify window size in the registry edit window to what you want, instead of deleting those entries. You might want to delete, 'Screenmanager Is Fullscreen mode' too, as that might being minimizing the window.

On macOS:
You'll need to edit the keys in the plist:
~/Library/Preferences/com.UnknownOriginGames.OddRealm.plist

On Linux:
You'll need to edit:
~/.config/unity3d/UnknownOriginGames/OddRealm

Let me know how it goes.
