QGIS Intersection is returning with an error

Question

I am trying to run "Intersection" on two different shapefiles (Shape1, Shape2). The first one is with the purple colour and the second with the blue.

Previously I've run "Check validity", "Multiparts to singleparts" and "Simplify geometries" just to make things more easy.

When I run Intersection between the two shapefiles I get the message "GEOS geoprocessing error: One or more input features have invalid geometry".

Update: After doing "Validity Check" I didn't had any "Invalid Output" results, only "Valid outuput" even after changing the "Method" from GEOS to QGIS and "the one selected in digitizing settings", so I do not really figured out what is the problem.

I am new at this. Any ideas please?

did you check this thread and the solution there: gis.stackexchange.com/questions/259256/… — eurojam
Yes! I checked it before posting this thread, so I' m gonna add that I didn't had any "Invalid output" from validity check so that people will know that the problem is somewhere else — Cornholio

Try using Saga GIS intersect tool in processing tools. If you have characters problems in output shape, change coding in layer properties
