Ciao,

You don't mention that you rebooted, so just try that first.  

sorry but I do not understand what you mean.

In any case i rebooted the system. ( restart )

Yes, thats what I meant.  Always the easiest thing to try.

 

The PharoLauncher  launch command on the Pharo 7.0 -64development image  report the same error.

I have some important work in the image ( and i don't have a backup )

Some consideration?

 I'm not in a position to diagnose the error, but perhaps help you recover your work.

In PharoLauncher, if you right-click on the image you are trying to launch,

then choose "Show in folder" then browse to "pharo-local/ombu-sessions"

and you should see some files.  If you create a fresh image and copy those to the same location there,

the go World menu > Tools > Code Changes and see if you find your work.

Check out the filters. Possibly useful...
