Start by reproducing the issue on Windows 11 with the 32-bit RetroArch build, NVDAControllerClient.dll, and accessibility_enable enabled. Then trace the accessibility_enable startup path and the 32-bit NVDA integration; done means NVDA works when launching the 32-bit build without breaking the reported startup behavior.
