SWBF2 Mod Tools VisualMunge fails to munge

[i2Bros]

As stated in the title I am stuck with this annoying issue: when I munge there is no actual munging. The VisualMunge goes on and it says it's completed, but munging times are too much short and ofc no munged file appears in the addon folder except for an empty folder named as "data_CWS", which is my mod name. I tried everything:
-new data_CWS built from scratch
-new mod tools installation
-manual clean of the munging files.

For the sake of your diagnosis, my operative system is Windows 10 Pro x64. Also I am using files from my past PC, nothing is new from scratch tbh. I really need help cause I am developing a really followed mod on moddb and people want to kill me already cause it's ages I am not uplaoding a thing.
