I'm trying to run the Merge tool on some rasters using Qgis 3.8 and when I add the layers as inputs, the tool just automatically closes... everytime, no matter which parameters I'm checking or unchecking. It doesn't show an error, it doesn't try to run the tool, the window just vanishes. It doesn't matter if I load from the layers in the layers panel or add them from files. As soon as I hit ok to add the input layers, the window is just gone.
Has anyone run into this behavior before and know a fix?
