This is a rare error message that will show up in your "Experts" tab on mt5. This error affects a very small amount of users (usually only Windows 11 users). Typically this error happens because of one or more of these reasons:
You are using a special version of MT5 not the official one
Your Windows is not fully up to date
Your latest version of MT5 is bugged and you need to rollback to a previous version
Make sure your windows is updated to the most recent version:
If you are on Windows 11 that is not version 22621 and above you will need to update your Windows. Please make sure your Windows version is up to date.
Make sure you are using the official MT5 and not a special version:
