Infinite loading is a common thing for skyrim.
Iirc it’s due to incorrect memory allocation.
There are several solutions you might want to try out.
SKSE allows setting a bigger initial memory allocation.
So does ENBoost if I’m not mistaken.
And if you already have SKSE you might want to try out SafetyLoad. You can find that on the nexus, that solved my load problems.
Edit:
Right after writing this I realized… you can’t use those with vorpx. xD
Sorry.
You might still look into the infinite loading screen problem on google. There are lots of guides out there that address it.
