When I download ENB v0.305 and extract the enblocal.ini file from the WrapperVersion folder, it tells me DataSyncMode=0.

It sounds like it could be a DynDOLOD issue. Have you tried disabling the DynDOLOD.esp and loading an exterior?

I would bet money that your problem is that your Stunning Statues of Skyrim SRLE installation is incorrect, or at the very least, the statue of dibella part is since her statue is in that area. Go back to the SRLE guide and follow the special instructions extra carefully, creating all the folders it wants. Afterwards, may have to generate DynDOLOD again.

Try disabling DynDOLOD.esp and see if you crash in the same spot.

I am not sure about the console commands messing up anything unless you go too fast. Wintermyst has a few speed enchantments, most useful would probably be fortify sprint speed for general running around. Ordinator's Windborne perk from Speech boosts speed 15% (and stacks it says) for 15 seconds after shouting. Apocalypse Magic's alteration spell Longstride grants 25% increased movement while concentrating. CACO adds fortify speed potions for sale/craft, the merchant ones I have seen range from 15% for 60 seconds to 60% for 120 seconds. Ordinator's Crimson Bull perk from Alchemy boosts speed 10% for 60 secs after consuming a beneficial potion/ingredient, and the Lab Skeever perk makes potions last 15x longer if consumed within 20 seconds after using an alchemy table. I usually grab Longstride ASAP and start using it, but Alchemy looks great too for later on.
