teensy4.1 and gdb still working?

Can anyone confirm that there is a setup which works with a Teensy 4.1?  My IDE version is 2.1, Teensyduino is 1.58, using Visual Studio 2022.  I installed the gdb stub library through VSMicro.  It compiles in debug mode, but the code that gets uploaded just produces a 7 or 8 blink error.  The only way out is a manual reset.

I will provide the info you referenced, but in the mean time I tried with a simple blink program and got a different result.  After compiling and choosing attach process, I got this:

unable to start debugging.  unexpected GDB output from command "-target-select remote \\.\COM31".  Remote replied unexpectedly to 'vMustReplyEmpty': timeout

You need to follow the guide in yellow. The output is too large to post into a forum thread. If you don't want to email then click Reply and then attach a file.
