MCUXpresso can't find JLink debugger

I've just upgraded to MCUXpresso 11.1.1, and to Segger JLink 6.63e. Now, MCUXpresso can't find the JLink debugger. I get this message when I try to debug:

No compatible probes available. They may be disabled, disconnected, not powered, already in use or not compatible with this target.

I've tried uninstalling MCUXpresso (which, by the way, takes many hours to complete!) and re-installing, but I get the same result. I can run JLink from the command line with no problem, including connecting to my target hardware. Ican also use JFlash to erase flash and program program it. The program flashed this way does run correctly.


Here's what I get in the console window when I try to add a JLink debug configuration and then debug with it:
