so the skse plugin responsible for my issue is"B:\Steam\steamapps\common\Enderal\Data\SKSE\Plugins\JContainers.dll" and removing it stops the crashing at the main menu, i'm gonna try updating it with the latest one from the nexus
---edit----
that seems to have fixed my issue
---edit-2---
more specifically the issue seems tto be that "Data\SKSE\Plugins\JCData\*" was missing
