Urban Morphology: Morp. Calc. (Grid) Execution failed

Hello,

I am doing the UMEP tutorials. In tutorial "Urban Heat Island TARGET", when I tried to derive roughness parameters using the Morphometric Calculator (Grid), I got this:

By the way, I have faced many issues regarding installation of UMEP plugin (I solved many of them by manual installation of specific versions of some libraries).

My guess is that you have an outdated version of your proj data database. I am not sure how to update this but try the network installer and update your proj-data. Below you see my installation regarding proj:
