Samsung Magician worked normally about a month ago, but it now reports a network problem and won't let me change any settings. I've tried reinstalling the software, allowing it through the firewall, running it as administrator, and even installing older versions, but the error remains. Has anyone found a reliable fix?

If you’re affected by this, removing Windows update KB5121003 reportedly resolves the problem. After uninstalling that update, Samsung Magician starts working normally again.
This seems to be connected to a recent Windows 11 security update rather than the Magician installation itself. Reinstalling the program or using an older version doesn’t appear to fix it.
