CTD's in the world, especially near the Falkreath DBH Sanctuary

[Lazerah]

So I've been having a bunch of issues recently with my newly installed skyrim and STEP 2.2.9.1.

 

I used STEP extended and I added a few other mods, this is my load order. https://pastebin.com/XMp6P68d

 

My game has been fairly fine through the Thieves guild questline, but as soon as I started the Dawnguard and Dark Brotherhood questlines I've been having CTD issues.

 

Most of the crashes have so far been on fast travelling to the Falkreath santuary or leaving the santuary, I've also had 1 or 2 more crashes just in the world during or shortly after the fight.

 

I can't really think of a culprit I was hoping someone here might have a clue, or spot a mod in my load order that conflicts.

 

I've also made sure that my memory is fine using memory blocks log.

 

Any help is appreciated, thank you.
