    A Lightroom Classic crash referencing ntdll.dll is a general application fault where the program unexpectedly closes due to a low-level memory or hardware conflict.

    Common Fixes

    • Disconnect Network Drives: Unplug or disconnect any mapped NAS drives or network storage, as unstable connections frequently trigger ntdll.dll faults in Lightroom Classic.
    • Reset Preferences: Hold Shift + Alt (Windows) while launching Lightroom Classic to reset your preferences to default.
    • Test a New Catalog: Create a brand-new, empty catalog and import a few photos to check if your main catalog file is corrupted.
    • Run System File Checker: Open Command Prompt as Administrator and run sfc /scannow to repair corrupted Windows system files.
