I'm trying to connect to a CCG6 device (CYPD6125) with PSoC Programmer and MiniProg4 and I'm getting a "Can't Open CMSIS-DAP port" error message. This is a older project but last time I connected just fine. Nothing has been done in about 1 year, no changes to software or board. I'm guessing a Windows update has broken something. How did I fix this?

I've tried unpowered and powered. It works fine if I used a different Windows computer. This is a program install issue.

What's your board's power source during programming? Can you please upload your PSoC Programmer screen capture?

I uninstalled all Cypress's stuff and reinstalled. Still not working. The hardware works fine on a different computer.

How about changing to another USB port on that computer?
