Make sure you have your FPS capped at 60fps. FPS over 60 Skyrim no likey. There is also a bug that causes spinning etc upon death if hit with a Paralysis spell. You might also want to try something like this https://www.nexusmods.com/skyrim/mods/83716

5 5 Unofficial Skyrim Special Edition Patch.esp? Are you playing Skyrim SE or Oldrym?

Its crashing DURING character creation correct? If so, Try this: https://www.nexusmods.com/skyrim/mods/33526/?tab=posts Also during character creation try to pop out of the racemenu mod to the normal vanilla part once in a while. I forget what the deal is but I think it uses more and more memory until it eventually crashes if ya stay in it too long. If you google "Skyrim racemenu crash" you will see a metric ass ton of posts about it.

Ok first off, verify your game files thru STEAM. (you will have to re clean your masters afterwards if you cleaned them) Well I'll be damned. Look what I just found... https://steamcommunity.com/sharedfiles/filedetails/?id=429076438 Well that saved me some typing.

What ENB are you using?

Go into... I think into your mod settings in game under SkyUI and there is an option to opt out of checking swf files for map, menus etc.

Are you using LOOT for load order? Have you checked for errors using TES5Edit as shown around minute 2 of this video: https://www.youtube.com/watch?v=cPwiY7NBVTM&list=PLAxUevXR_SD2ICe3ioc0zeIQJvrBklzUu&index=2&t=162s Using Safety Load? https://www.nexusmods.com/skyrim/mods/46465 Performance monitor? https://www.nexusmods.com/skyrim/mods/6491 SKSE installed and updated? Have you made any ini changes? Ugrids etc

Did you cap your FPS to 60? Skyrim engine no likey higher FPS's.

Make sure Steam is running and minimized.

Your very welcome. Have a great X-Mas!

You could just download Afterburner and just use it to cap your FPS and leave everything else alone. Skyrim seems to run best under 60fps Heres a video showing how to do it: https://www.youtube.com/watch?v=hQ5CH1yMZ9s Heres a download link: https://www.guru3d.com/files-details/msi-afterburner-beta-download.html

I would start uninstalling mod starting with the last you installed. In clumps maybe 5 at a time until the game runs. Then ya can narrow it down to which is the problem. Your using some sort of manager right? And SKSE is installed?

Have you tried this: https://www.nexusmods.com/skyrimspecialedition/mods/1918 and https://www.nexusmods.com/skyrim/mods/46465?tab=posts Will need more info beyond that.

I don't know how helpful papyrus really is for crashes. Start with the basics. Watch this video. At about 2:00 he shows how to use TES5Edit to check for errors https://www.youtube.com/watch?v=cPwiY7NBVTM&index=2&list=PLAxUevXR_SD2ICe3ioc0zeIQJvrBklzUu&t=168s Do you use LOOT or something like it for load order? What mods are you using/load order? PC specs?

After a google search looks like FNIS installs them in The "animations" folder under Meshes > actor > character is created by FNIS
