GRASS not working with QGIS 3.6

I updated QGIS to version 3.6 using OSGEO4w

When I try to run any GRASS script, I get the following error message :

This algorithm cannot be run :-( The specified GRASS 7 folder "C:\OSGEO4~1\bin\bin" does not contain a valid set of GRASS 7 modules. Please, go to the Processing settings dialog, and check that the GRASS 7 folder is correctly configured

It looks like the path doesn't exist, but I couldn't find a place to change it; it is not an option in the processing settings any more like in versions 2.x.

Is there a way to run those processing scripts in QGIS 3.6 and if so, how could I tweak the settings needed?

Edit : Here is what my processing options looks like

If I open QGIS with the shortcut "QGIS Desktop 3.6.0 with GRASS 7.6.0" everything works fine. If I open QGIS with the shortcut "QGIS Desktop 3.6.0" I get the same error as you
