What was the recent upgrade you performed after which this error appeared?
Can you post the complete output in the CCS build console? You can copy and save it to a text file and then attach it here. Also please attach a screenshot of the build variables in CCS (with system variables enabled) of the section where CG_TOOL_HEX and similar variables are defined.

My guess is one of your system variables is incorrect. That's why it would be good to see them.
Thanks and regards,
