What are the recommended steps to diagnose and resolve this error, and if it results in system instability or data loss, how can Stellar Data Recovery help in recovering important files safely?

Error 0xc000001d usually points to a bad instruction error, most often caused by a buggy update, incompatible app, corrupted system files, or outdated BIOS on Windows 11. I’d start by uninstalling any recent updates or apps, updating chipset and BIOS if available, and running SFC and DISM to clean up system files. If it only happens with one app, reinstall that app or check if it’s compatible with your CPU. If crashes make the system unstable, back up your files first using Safe Mode, Windows Recovery, or a Linux USB. Only if files are missing or corrupted after the crashes would Stellar Data Recovery be useful to safely pull readable data before deeper fixes or a reinstall.
