If you cannot copy from Primary to Secondary it is probably the firewall on the primary that is causing the problem as a connection is made back to the primary for clipboard information.

I have been able to see this issue on that insider preview of Windows (a test box).  You can copy paste text, and drag and drop files, but copy / paste from desktop to desktop has an audible ding but no error message.

It would appear that MS has some things to work out with that build.

I don't know of a situation where it has not been solved for anyone that reported it.  It is almost always a Windows Firewall issue:

While we cannot support insider builds (for clear reasons), what are you trying to copy \ paste? Are you using Ctrl + V or the right click context menu?  If the latter, does "Paste' show as a highlighted option or is it grayed out?

So, I have the same issue and I am NOT using the insider version of windows 11.

Windows Firewall is off, I have run the batchfile to fix the ports on both PCs.

I can copy from the secondary to the primary with no issues, but as soon as I try from primary to secondary it locks up whatever app I am pasting into.

I suddenly cannot copy and paste from Primary to Secondary Computer.

Primary Computer has Windows 11, Secondary Computer has Windows 10.

I can copy and paste from Secondary to Primary, but not Primary to Secondary.  However, when I turn off Windows Firewall on Primary, I can then copy and paste from Primary to Secondary.  As soon as I turn the firewall back on, I can no longer copy from Primary to Secondary.

I tried to follow your previous instructions.  No luck.  I have installed your MPPortFix multiple times on both computers, but with no luck.  I tweaked the Firewall settings as you instructed.  No luck.  I give up.

Can you please tell me how to fix this problem??????  HELP!  It's driving me crazy!!!

Thank you very much!

I do not have any VPN connections to disable.  What next????

Your Windows 11 machine is probably set to have your network as a public one not private/work.  Doing so will block the rules set.  If you set your network to private it should resolve the problem.

For copying from a primary to a secondary the secondary must connect to the primary and this requires the firewall to allow it.  If it does not then there will be a timeout on the copy operation which will pause the app requesting the data until it has hit the timeout.
