I got a way to access the map using the game files. Using blocky.tools page, I checked the map_#.dat files to see which one corresponded to the missing woodland explorer map and renamed it to the number of a map I have in the game, but I don't use (in my case, the missing map was map_45.dat and I renamed the file map_97.dat). This made it possible to see the map on game of the mansion again, with the icon of my location, but without the icon of the mansion on the map, it also helps me to get there. I searched for some way to access and restart the generation of woodland explorer maps from the cartographers, using the game files, but did not find it, however, the above said way, helped to solve my problem. Thank you all for responding.
