Probe_Basic Not Writing Parameter Variables

Good Morning,

I've installed Probe Basic and continue to have an issue with parameters not being written to the .var file. Anytime a value is updated via Probe_basic ui, a "File not Open" error shows and no changes are made to the .var file. Parameters entered via Gcodes work fine. For instance, SET TOOL TOUCH OFF POS generates "File Not Open" error, but MDI g30.1 works fine. The sim version works fine. 

Terminal shows: emctask.cc 68: interp_error

I am running:
Debian 12 Bookworm
LCNC v2.10
Current version of Probe_basic and QtPyVCP
installed sable APT version 

Any help would be greatly appreciated. 

Thank you,
Sean

  

Does the sim work? If so its a configuration problem.
