See my response in the other thread. This morning, no debug configurations were working at all.
@Alice:
On MCUXpresso IDE, we recommend using Quickstart Panel to build , debug and so on .
On MCUXpresso IDE v10.2.0. you can directly click "Debug" button, it will search the
The blue debug button was disabled completely this morning.


You can see my other thread for more details..
The Quickstart panel seems like an inadequate tool for real development work. Please understand that I mean this as feedback and not criticism, but here's my opinion on a quickstart panel.
To me, a quickstart is for one of two things: Either getting new users started quickly with the basics, or giving regular users a single place to access the most commonly used tools. In the latter case, I'd expect all of the tools to be available elsewhere.
The first three options deal with new projects and importing examples. These are common beginner activities, and it's exactly what you'd want for a classroom environment where you're starting a new project every class. It also looks like a good way for hobbyists transitioning from Arduino or a similar environment to get started without so many confusing options.
Importing an example or starting a new project are things I might do a few times per year. That quickstart panel occupies a large chunk of valuable screen space for exactly two buttons (build and debug) that I need access to frequently, and I use keyboard shortcuts for those. With the cute little bug and hammer icons it frankly feels a little infantile.
I don't want a quickstart panel occupying space at all, and I certainly don't want to be forced to use it for routine tasks. I can put that space to better use with the Git staging view, or my own script launching page that handles packaging firmware builds and posting them to the server.
And aside from that, just now it's not even working:

The green debug button is working. The blue one gives me the 'Debug MCUXpresso project is currently disabled' error, and the one in the quickstart panel is disabled.
