@Electrodydy @chunkyseal235 I'm sorry to hear you're both having trouble starting up the game, and I'm happy to look into this with you! To begin, let's rule out a few common causes of launch failures like this. Please try the steps in our basic troubleshooting guide (if you haven't yet done so) to ensure we've set a baseline in case the issue continues.
Also, I recommend that the game and Ubisoft Connect be installed together on the same drive on your computer, preferably the same drive that Windows is installed on. Next, disable background applications to rule out conflicting software. During this, please be sure to disable any overlays you have active as a test. Lastly, please empty the cache of Ubisoft Connect to clear files that may be corrupted or non-functioning.
Should the issue continue after these steps, please update us here if you're still having some trouble so this can get reported. Thanks for working with me on this!
