Confidence

Memory address 0198090 on Skyrim SE 1.6.640 is the definitive engine signature for a plugin authored in the new 1.71 ESL header format (introduced in Bethesda update 1.6.1130). Your game version cannot allocate the extended form ID ranges without the Backported Extended ESL Support runtime patch, causing an immediate CTD directly as the engine initializes plugin records right after the ENBSeries graphic banner is painted.

Authoritative Crash Logger Recommendation

For Skyrim 1.6.640 (AE): Install Crash Logger SSE AE VR by alandtse. Pair it with the Mod Organizer 2 Crash Log Reader plugin. Raw, unanalyzed call stacks are required to isolate DLL fault offsets.

Warning: Avoid using Trainwreck or online pre-filtered AI log analyzers. They strip stack traces, registers, and module offsets essential for finding memory hooks.

Wabbajack Manual Override Inspector

When Wabbajack prompts for manual downloads (e.g. High Poly Head v1.4 from VectorPlexus): ensure the zip is dropped in your Wabbajack downloads directory, or installed directly into the designated MO2 separator without disabling its master ESPs (High Poly Head.esm).

Load Order Anchor: Keep High Poly Head.esm in early master block.
