File Explorer Keeps Crashing

Try restarting it from Task Manager (Ctrl+Shift+Esc) and clearing File Explorer history via the Folder Options control panel. If the issue persists, run the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tool from an administrator Command Prompt to check for corrupted system files. If none of these steps work, you may have a corrupt driver, corrupted system file, or a problematic Windows update, which can be addressed by uninstalling the update, testing a different user profile, or running sfc /scannow and DISM commands to repair system files. 

To resolve issues when SFC (System File Checker) cannot fix corrupt files, first run the DISM (Deployment Image Servicing and Management) tool using the command DISM /Online /Cleanup-Image /RestoreHealth in an elevated Command Prompt, then retry the sfc /scannow command. If the problem persists, check the CBS.log file for specific errors, consider running chkdsk /f to check the disk for errors, or perform an in-place upgrade to replace the operating system files while keeping your personal data and applications
