Skyrim SE is great, but one needs the unofficial patch to get rid of all the mess. Make sure it is in the top of the list and there are no mods before it. Then go to the console and hold the xbox button until the console shuts off. After 1/2 minutes turn the console back on to get the green screen. This will clear your cache and your game should run fine. I run 24/26 mods on the xbox and I am also an author. When one uses mods, they should make a test character and see what mods they want. The unofficial patch is a must for better game play. You will notice the difference. After you download, delete, download, delete, your character becomes corrupt which is why it is a test character. When you have the mods you desire, delete all your saves, and do the green screen thing. Then make your character. You will enjoy the game better.
Hope that helps.
