DaVinci Resolve Crashing During H.264 Export on Windows 11

I'm using DaVinci Resolve 18.6 on Windows 11, and every time I try to export a project in H.264 or H.265, Resolve crashes halfway through. I’ve tried clearing the render cache, switching GPU settings, and updating drivers, but the issue persists. It only happens with these formats; other codecs like ProRes and DNxHR work fine. Any advice on resolving this?
