Crash on world load: BEX64 in sable_rapier_x86_64_windows.dll (Rapier3D.initialize) - Sable 2.0.3 + Create Aeronautics 1.3.0 / NeoForge 1.21.1 #1269
Description
Context
What I was doing:
I created a new world with Sable 2.0.3 and Create Aeronautics 1.3.0 on NeoForge 1.21.1. The game crashes immediately when the world loads, specifically during the initialization of the Rapier physics pipeline (Rapier3D.initialize). The crash is reproducible 100% of the time. Sometimes, after a crash and cleaning the .sable folder, the world loads once, but on subsequent re-entry, it crashes again.
What I've already tried:
- Changing Java runtime (Microsoft OpenJDK → Eclipse Temurin 21.0.11)
- Reducing/increasing memory (-Xmx8192M, -Xmx10000M)
- Disabling sound (all volume sliders to 0)
- Disabling AVX512 (via BIOS)
- Removing all other mods (only Sable + Create Aeronautics left)
- Deleting the
.sablefolder and letting it regenerate - Adding the
.sablefolder andsable_rapier_x86_64_windows.dllto Windows Defender exclusions - Checking for hanging
javaw.exeprocesses in Task Manager - Trying older Sable versions (1.1.3, 1.2.2) – same crash
System information:
- OS: Windows 11 Pro (24H2, Build 26100.8521)
- CPU: AMD Ryzen 7 7800X3D
- GPU: NVIDIA GeForce RTX 5070 Ti (driver 610.62)
- RAM: 32 GB
- Java: Eclipse Adoptium Temurin 21.0.11+10 (64-bit)
- Mod loader: NeoForge 21.1.233
- Sable version: 2.0.3 (also tested 1.2.2 and 1.1.3)
- Create Aeronautics: 1.3.0
- Other mods: Create 6.0.10, Flywheel 1.0.6, Sodium 0.8.12 (and dependencies) – but crash also occurs without Sodium.
Crash details:
- Java error:
EXCEPTION_UNCAUGHT_CXX_EXCEPTION (0xe06d7363)insable_rapier_x86_64_windows.dllatRapier3D.initialize - Windows Event Log:
BEX64(0xc0000409) inOpenAL.dll(offset 0xa2b05) – but this seems collateral, as the crash originates in Rapier.
Additional notes:
I have seen similar reports from other users (e.g., issue #1016 and others). The crash appears to be related to the native library loading and initialization on Windows. The fix for path resolution in #1016 did not resolve the issue for me.

I had the same problem, but I deleted the file(sable_rapier_x86_64_windows.dll), and the DLL regenerated,the game could continue running.

I'm having the exact same issue, word for word. The game crashes when the world loading screen reaches 0%, Java reports EXCEPTION_UNCAUGHT_CXX_EXCEPTION, and the Event Viewer reports that the issue is with OpenAL.dll. I've tried deleting the .sable cache, reinstalling Sable, running only Sable, and changing my instance configuration, yet nothing works. However, I am able to run older versions of Sable. I've tested v1.02 and it works fine (its the only other version I've tried besides 2.02, which also gave the same crash). Strangely, I had no issues with the mod up until about 3 days ago, when something changed, either a change in my JRE (I'm pretty sure I don't have auto-updates enabled though), or some silent Windows update (I'm hesitant to believe this too, as I've seen Mac users with similar issues).

We hit the same
Rapier3D.initialize/EXCEPTION_UNCAUGHT_CXX_EXCEPTION(hs_err) symptom on Windows and traced one reproducible cause:Repro: launch via CurseForge → join world (OK) → leave world → close CurseForge/Overwolf while Minecraft stays open → join world again → hard JVM crash in
sable_rapierduringinitialize.Cause: closing the launcher breaks Minecraft’s stdout pipe.
fernthen panics oninfo!("Rapier scene initialized")with Windows os error 232 (“pipe is being closed”), even though the physics scene was already constructed. That panic crossed JNI and killed the JVM with no Minecraft crash report.Fix: #1448
catch_unwindaroundinitialize(same pattern astick/step) so panics become Java exceptions / crash reportsVerified locally with a rebuilt Windows native: after closing the launcher, world join succeeds.
This may not cover every report on this issue (e.g. other BEX64 / OpenAL cases), but it should help anyone hitting the launcher-closed-stdout path, and the
catch_unwindmakes remaininginitializepanics diagnosable.iPyrrebpsaR-2 commentedon Aug 7, 2026
I can confirm the issue lies with Curseforge. I forgot to post here, but installing sable via Modrinth fixes the issue. Its strange though, as the crash occurs when using any launcher, as long as the the mod is installed via CurseForge. Glad to hear its being fixed now!
JoaoVitorBaggio commentedon Aug 8, 2026
I’ve tested this on both the Modrinth App and CurseForge/Overwolf. The Sable 2.0.3 jars from CurseForge and Modrinth are byte-identical, so the store source doesn’t look like the distinguishing factor. With the stock jar, the hard crash still happens under the same condition on both launchers: joining a world after the launcher was closed while Minecraft stayed open. With a build that includes the closed-stdout / Rapier-init fix (PR #1448), that repro no longer hard-crashes.
So it may be that something like that was happening on your side without it being obvious, or that you’re hitting a different root cause with the same symptom.
