gdb-server program client error Error: read ECONNRESET

I'm using this plugin in an educational environment with many many intallations on Windows, MAC and Linux together with xpack-openocd and a st32 nucleo board. For many semesters I had no problem (so many thanks for this). In the last fall and now I had/have one student with a non working setup on Windows an following problem:

All Paths are well set.
Starting openocd and remote gdb session on console on console works.
OS: Windows
xpack-openocd version 0.11.0-3 and 0.12.0-2. Both don't work.
vscode: 1.87.1
I'm not able to reproduce it on my linux installation nor have other students problems with the same setup.
Both gdb and openocd seem to be started but operation exits with following message:
