Things are going to break, please only change locale by creating wxLocale objects to avoid this!"

My OS is Windows 10 64bits. The Grass installation was made with OSGeo4w. The Grass v is 7.8.7. I tried reinstalling Grass but still dont work. Also i tried installing other grass versions but they don't work either.

Not reproducible on my system (Windows 10 64 bit) with the latest grass 7.8.7-4 package (installed as a dependency of the qgis-full and qgis-ltr-full packages).
