Moving to Windows 11, strange behavior

I've finally moved to Windows 11, I reinstalled version 6.90, and I get this strange behavior in the download folder after clicking on the nzb (because windows 11 will not automatically invoke newsbin)
It will put every .rar file, except for one random .rar in the first directory. It then puts one random .rar in a second directory, so the autopar always fails. Has anyone else seen this behavior?
