Users frequently encounter issues where the game won't launch or mods stop working following these specific updates.

Mod Compatibility (Script Hook RDR2): If your game fails to open after updating to Build 1491, it is usually due to an outdated Script Hook RDR2. You must download the updated version (often referred to as Script Hook RDR2 V2) and place the ScriptHookRDR2.dll in your main game directory. red dead redemption 2 update 131123 149150 work

Vulkan Cache Crashes: If the game crashes on startup without mods, it may be due to corrupted cached data in the Vulkan API. A common fix is to delete all SGA files located in Documents\Rockstar Games\RDR2\Settings.

Graphics API Settings: For those using mods, ensure your Advanced Graphics settings are unlocked and set to the Vulkan API, as DirectX 12 is often incompatible with certain mod loaders. Red Dead Online Content Additions

While major content updates have slowed, Title Update 1.31 introduced:

New Telegram Missions: Three "Hardcore" co-op missions—In Bad Faith, Strong Medicine, and Sow and Reap—playable solo or with up to four players.

3. Making Mods Work (The "Work" Part)

If you are searching for this specific build number, you are likely trying to configure Script Hook RDR2 or Lenny's Mod Loader (LML). Go to your Library

The Problem: Mod tools bind to the specific game .exe build. When Rockstar updates the game, the hash changes (e.g., from 131123 to a newer number), and old mods stop working.
The Solution:
1. Check your game version in the bottom right corner of the main menu (it should read v1.0.1311.23).
2. Download the latest Script Hook RDR2 and LML from their respective websites (e.g., Nexus Mods or the official dev sites).
3. Update the "version.dll": If you are using a specific version.dll file provided by a modder for build 149150, ensure that file is placed directly in your main RDR2 game folder (where RDR2.exe is located).

If the game crashes on launch:

You have a mod file intended for a different version. Remove all .asi and .dll files from your game folder and verify files via Steam/Launcher to get a clean slate, then download the mods updated for the current build.
