Hello,
Thank you for posting in Q&A forum.
- It is recommended that you disable all antivirus/security programs or temporarily uninstall them and then repeat the DISM scan to see if it works.
- Confirm that your operating system has all the latest updates installed. Sometimes, DISM issues can be caused by known system vulnerabilities that may have been fixed in subsequent updates. Check for and install all available updates via Windows Update.
- The correct way to run DISM at the same time is to run Command Prompt as administrator and enter the DISM command.
It is also recommended to refer to the following links to provide more solutions: Best Fixes: DISM /online /cleanup-image /restorehealth Is Stuck - MiniTool,How to Fix: DISM Failed On Windows 10/8/7 Computer - MiniTool
I hope the information above is helpful.
Best Regards,
Yanhong Liu
