+
+_**User (2026-01-01 21:25Z)**_
+
+can you look at `Glamrock Freddy PnS.blend` to see what version of blender it was created in? `Glamrock Freddy.blend` was made in bl 3.0, but PnS appears to be compressed, so I can't read its header. I have blender on PATH so it should be easy.

+PATH updated. Blender 5.0.1 is now on PATH (replacing 4.5).
+
+The change is in the User environment variables. You may need to restart your terminal or IDE for it to take effect in other sessions. The current session has been refreshed and `blender --version` shows **Blender 5.0.1**.

+## Crash summary
+
+**Blender version**: 5.0.1
+
+**What happened**:
+- Access violation (0xc0000005) during a read at address `0x0000000000000138` (null pointer + offset).
+- Occurred in the Vulkan graphics backend while syncing the backbuffer during a viewport update.
+
+**Last operation before crash**:
+- Material preview refresh completed: "Material previews refreshed (7 materials)".
+- Crash happened during the subsequent viewport redraw.
+
+**Stack trace**:
+```
+blender::gpu::VKContext::sync_backbuffer
+GHOST_ContextVK::swapBufferAcquire
+wm_draw_update
+WM_main
+```
+
+**Likely cause**:
+- Vulkan context issue: invalid/null handle or resource during backbuffer sync.
+- Possible driver/graphics state problem, especially with NVIDIA (nvoglv64.dll, nvwgf2umx.dll loaded).
+
+**Recommendations**:
+1. Update GPU drivers (NVIDIA).
+2. Try a different render backend (OpenGL) in Preferences → System → Cycles Render Devices.
+3. Report to Blender if it reproduces (5.0.1 is recent).
+4. Save frequently; this can occur during viewport updates.
+
+This looks like a graphics driver/Vulkan backend issue rather than a problem with your blend file.
