Same thing here. Did you ever get that to work? Could not get that to work either. The cost of the hours involved in that made me decide to, for now, go back to MS Project 2002 (still works in win11).
Another thing I could not get working in ProjectLibre is the zoom function. Only works in the chart space, not the sheet. Getting bigger text seems not to be possible from within the application.
Also, not being able to select multiple tasks to change their resources (or whatever) all at once is not possible. ProjectLibre seems to require doing that sort of thing one by one.
Appreciate the initiative, would be happy to donate, but for now it is below expectations. I’ll keep trying to get it working, but for now . . .
