So I tried to give my game a little test run, but instead it crashed and gave me this error;

Error launching game: Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies. The specified module could not be found.

Error launching game: Object reference not set to an instance of an object.

System.NullReferenceException: Object reference not set to an instance of an object.

Someone else had the same issue awhile back, I'll link it here ; http://textadventures.co.uk/forum/quest/topic/-jkuhmhdhus5tjaxu0_cbw/error-with-new-version

I've tried uninstalling and reinstalling, but the issue still persists. Anyone else have this issue, and if so, have any of you managed to solve it?

Hello.

Did you try downloading Quest again and installing from that newly downloaded .exe file? (That has worked for someone before.)

I have, and the issue still persists.

I made sure to uninstall it, download it again from the website, and reinstall it from the new .exe file.
