Infinite loading while fast moving

I ran into such a problem when quickly moving to any location, there is an endless download, but when walking on my own, everything is fine. And the endless download even in the test room.
There is a mod manager, all mods are sorted by loot.

There is an unofficial patch

Loot writes that there are no conflicts. Worth a bashed patch. fnis generated. And there is a namesis also generated.

Cleaned save from scripts.

Infinite loading does not freeze the game, but just endlessly shows the loading screen with a 3d model and text (Standard loading)

What can I do?
Skyrim AE 1.6.353, skyui. skse latest version of steam.
The files have been verified.
I looked for forums that there is a saftyload, but it works under the current legendary edition.

Is there any solution?.
