(26June2020) This maybe a bit premature but my issue fits in with this post but since this post has over 25 pages of submissions I only got to page 13. At page 13, I was able to figure out and resolve my issue but I have not fully tested it (over 100 hours of game play). Previously I had tried all sorts of loading orders, installations and re-installations of Mods, used "TOOL" to sort my load order, rebuilt my MOD list from ground up following every line of instructions, requirements, dependencies and compatibility recommendations, Performed new install of Skyrim SE - so forth and so on, multiple times, and nothing worked. One member in this thread named "BlueGunk" mentioned that her issue was still on going and she fixed it by disabling her PC Head Tracking software Mod. Well this triggered an experience I had many years ago with a PC Steam game that was ported over from an XBOX Game Console which caused my mouse to become erratic and it was impossible to play the game after install. I eventually found out the cause of the mouse conflict with that game was my H.O.T.A.S. system. I disconnected both USB H.O.T.A.S. controllers on the back of my PC and the problem went away. Well Success Has Arrived! That same problem caused my issue here with Skyrim Special Edition Mods (not able to save after x amount of playtime). The fact is I was getting conflicts like main menus (in "Immersive Horses") not working in game after enabling them in MCM for those Mods but Sub Functions of those same Mods work fine. I have not tried your fix here "squireoivanhoe" but your post lead me to my fix and I felt compelled to share my findings with your readers who are seeking a fix for their issue; hope this helps others in the future. Try disconnecting and or powering off any gaming Peripherals/Devices you have on your PC... Success Ends (28June2020)! Doesn't appear to have sustained long term success; for that I'm sorry. New Success Begins (29June2020)! I recently found this and it allowed me to save over a previously known faulty game load with all MODs enabled. I don't know how long this will last either....

To demonstrate that the NMM Custom Launch Command feature works do this: 1) Open NMM then "Settings" (at top of menu bar) + "Fallout: New Vegas" (Tab). 2) Enter "nvse_loader.exe" (without quotes) into the "Command:" field under "Custom Launch Command" + "Ok". 3) Launch game using the drop down selection (from the menu bar) "Launch Custom Fallout: New Vegas". 4) Test NVSE has loaded properly by: bring up the games Command Console and type "getnvseversion" + "enter".
