Missing G-code Burning stopped

I have recently changed computer,
and now when I import a .jpg image
to burn with eg the “jarvis” setting,
I get an error message stating that
incorrect G codes are being generated,
and the burning is stoped.
See the printout of the G-code file below.
Could there be a driver missing?
My controller is ANNOY TOOLS GRBL 1.1
I run Windows 11 Pro

Grbl 1.1f [‘$’ for help]

As a start check if you have enabled GCode Clustering.

Also try exporting your prefs from the old computer and importing them on the new.
