I am new to QGIS and want to learn some basic tools. However, after software installation I cannot execute any tool from the processing toolbox. All the tools is giving me the same error:
The following layers were not correctly generated. You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm.
The only tools which I could successfully perform so far are Contour tool and Clip raster by extent tool from Raster - Extraction tab.
Below is the example log for Line Smoothing tool:
