Ok, I fixed the problem. I had to uninstall Skyrim SE and Steam, then check to make sure the the game would load without mods. Then I tested each mod individually, to see if the game would play. The mod from the Skyrim SE game kept the game from launching. Also, one mod was apparently for the original Skyrim game, and one of my mods would only work from the Skyrim SE game. I am confused as to why it launched before. Thank you for your help! I hope my game continues to launch now that I have made these changes.
