On a fresh Windows 10 setup, running MCUXpresso IDE v10.2.1 [Build 795] I cannot debug my LPCXpresso V2 boards LPC11U68 or LPC1549. Both Debug Probes show up fine as LPC-LINK2 CMSIS-DAP V5.183 with no driver errors.


The same boards with same cables work OK on a different PC with Win8. They also worked fine on the previous Win10 PC that I used.


In the past 4 hours I tried to update BIOS, uninstall-reinstall MCUXpresso, started numerous fresh workspaces with freshly imported sample projects, deleted .launch files, enable/disable Vector Catch option, Pull ISP on Reset option disabled, 

I have found others have had this issue but I haven't been able to find a solution. Please help.

I get the following messages after hitting the Debug button:
