Hi,

It looks like the ${jlink_path} variable is not set. You can set the ${jlink_path} and ${jlink_gdbserver} variable globally (for all projects) in preferences:

Then make sure to set the jlink link exectuable is set with ${jlink_path}/${jlink_gdbserver} as shown below:

Please upload the console log.

The console log is likely showing garbage characters from SWO or semihosting, you can disable those options in the debug launcher configuration. Please post a screenshot of the core registers, it might reveal what state the program is in.
