Hi there,
SO, just a general observation. I would check what the versions of OpenOCD is installed. In all the SEEED debugger and PLio work-outs it was an issue. (PLio Version was old) I finally switched to OpenOcd for windows XPack and used the external commands. then added them to the Platform.ini file to wrap it up. 
"
C:\openocd\bin>openocd -v
xPack Open On-Chip Debugger 0.12.0+dev-01850-geb6f2745b-dirty (2025-02-07-10:08)

For bug reports, read
OpenOCD: Bug Reporting
C:\openocd\bin>"
and PATH , be sure the stuff you need is in the PATH or it almost never works. LOL 
for me.
I find this being the biggest problem on Systems with several Dev Systems and environments.
