Isaac Sim 5.1.0 GUI mode segfaults on Blackwell GPUs (RTX 50-series, including the RTX 5070 Ti) when running under NVIDIA driver 595.x, crashing inside the Vulkan rendering path a few seconds after the app loads — headless mode is unaffected since it uses a different renderer (D3D12 on Windows; on Linux, the crash is specific to the interactive viewport's RTX scene renderer, matching what we hit here). A user on the NVIDIA Developer Forums confirmed downgrading from driver 595.79 to 591.74 "resolves the issue completely," with both GUI and headless modes working afterward on the same RTX 5070 Ti. NVIDIA staff responded in that thread that 595.79 and 591.74 are both newer than Isaac Sim 5.1's actual validated driver range, officially recommending the 580.88 branch instead — which is the fix we applied here (580.159.03, a later point release on that same validated branch) and confirmed working.
