I'm using Windows 11, and I'm pretty sure the folder has full control permission. I'm not sure how accessing the scripts folder would help so I've tried downloading the Steam version first and now it's even worse, the game window closes itself immediately after launching it OR the original version, and uninstalling either one doesn't seem to fix it. Hope this helps.
Hmm, that's odd. I have no logging on disk currently for the game, so remote debugging is even harder. I am currently working on a new version and I'll add detailed logging then. My first guess it that something is not working due to the latest seasonal event update. I guess when trying to fetch quests from the web server there is some issue with it. If a quest script is errorneously stored then this might explain why it shows script errors. Can you make a screenshot of the debug console showing the scripts error and post it here? This would help alot.
