mod organizer Crash to Desktop when launching Skyrim SE through Mod Organizer 2

[CayugaDuck]

I am having a strange crash-to-desktop error when trying to boot skyrim through MO2. Whether I try and run the game through skse_64 or the regular launcher through MO2, the game boots until the Bethesda logo, then crashes to desktop before the main menu.

The same error occurs when I tried to make a new instance with no mods, both for skse launcher and the regular skyrim launcher through MO2.

The game is able to successfully boot to the main menu if I launch the game from steam (and I am able to start a new game fine), or directly run the skse_64 exe from my files. 

Another strange quirk is that other applications like FNIS and LOOT crash when I attempt to run their functionality. FNIS crashes when I click “generate” and LOOT crashes when I try to sort the load order.  

I tried to see if it was a strict MO2 issue by seeing if my modded FO4 would run, which it did perfectly. Other than the inability to fully boot Skyrim, I cannot tell if there are any other issues with my mods or load order or anything as the crash doesn’t return any error message.

I have tried reinstalling SKSE, I updated MO2 to the latest version, and completely uninstalled and reinstalled Skyrim, to no avail. My game was working fine last I played in late September, since then I haven’t touched anything. All I have done was set my skyrim steam appmanifest file to read only to avoid updates, which hasn’t been a problem on the past. I am truly lost as to what the issue could be.

If you require additional information from me, I’d be happy to provide.

If Skyrim SE crashes on launch through MO2, try checking for missing or corrupted mods. Sometimes, large mod files can get corrupted during downloads. I recommend using Filemail to transfer and back up large mod files without compression or corruption risks. Hope this helps!

Edit: I forgot to ask, have you resolved it?

Hard to say what is causing this, but I would start with asking the usual questions:

Is MO2 and the game installed outside any Windows protected folders. Like Program Files.

Have you created a new profile and disabled all mods, including skse, and tried to launch the game from the launcher?

Sometimes Windows has a habit of quarantining  usvfs_proxy_x64.exe. Check that this is not the case.,
