When I run a model with the green arrow to the right of the file path selected, QGIS freezes.

This seems to happen with any data or model that I use. I have tried several SHP files and models and QGIS still freezes. Try with the road network from http://download.geofabrik.de/europe/liechtenstein.html for example. I have attached a simple model.

the point is that that green arrow serves to run the tool/model iterating all input features. If input features are a lot the preparation phase take a long, it you leave it do its thing long enough at same point the tool/model starts.
