MIDI Inputs and MIDI Output blocks

Hello,
I’m just checking if anyone has bumped into the following issue on Windows 11 Pro and if there is a fix for it.
I have a Korg Nautilus that I have been using on my Windows 10 Home laptop and my Windows 11 Pro desktop. Something appears to have changed on the Windows 11 desktop but I’m not sure what or how.
I have not booted the Windows 11 system for a couple weeks, just got out of the hospital.
Previously to 2 weeks ago, I would see the the MIDI In and MIDI Out blocks labeled with NAUTILUS by default. The right click MIDI Inputs would have a choice of Nautilus and the MIDI Out block would have Nautilus 1 Sound. This is how it is working on the Windows 10 Home laptop but I cannot figure out why Windows 11 no longer has the choices it used to.
My MPK249 is recoginzed when loading older projects, but the Nautilus no longer appears like it used to and it is now just a MIDI In block and the Nautilus does not play the VSTs. Another weird thing is if I drop a MIDI In for my UR242 and connect it the Nautilus will play the VSTs.
I checked the drivers for my Steinberg UR44C and it is the same on both systems. I tried uninstalling and reinstalling but no luck so far.
I did update to the latest GP .20 today on both systems so that is not a problem.
Just seems like Windows 11 or AI took over and made a mess.
Any ideas to fix would be greatly appreciated.
Thanks!

Under Options > MIDI Ports, is your Nautilus selected?

Sorry for the delay getting back to you. Been busy with other things.
The ports were not showing up on my Windows 11 Pro desktop but were on my Windows 10 Home laptop.

The issue is that Windows 11 Pro can’t handle MIDI devices properly. It appears to create duplicate devices. I found the following from KORG that has the instructions I needed to get back to normal.

I had to remove some duplicate entries and others that are not needed.

Thanks for your help.

I’ve found this utility helpful for such things over the years.

I know MS plans to stop supporting Win10 but but for most people, and particularly anyone using their computer only for music, I’m not sure there is really any benefit in moving to Win11, which seems to be causing a lot of grief. As long as you’ve got a decent firewall and AV program and you don’t do random surfing or open unknown attachments, etc, just keep a full backup.

Win11 seems to have lots of issues.

I don’t think the problem is limited to Windows 11, which I’ve been using for several years without any problems and which I find more efficient than Windows 10.
On the other hand, I’ve always had problems with Korg products and their annoying drivers, since Windows 98 and all subsequent versions.
I’ve spent countless hours trying to solve problems with usb connections or the cohabitation of several Korg devices.
