Using windows 10,1.16.40 and i cant find my folder in file explorer. Have tried to use WIN+R and typing in %appdata% and all that kinda stuff. Hidden files is on. Tried different c combinations of folders (such as: Microsoft, windows etc ) still zero luck.
Something you might've not tried is finding the folder manually. Go to "This pc">(drive windows is installed on)> "Users">(your user), Now make sure that in the "view" tab in explorer, that "hidden items" checkbox is checked. A folder named "App data" should appear, and it's translucent. Open it, then the folder named "roaming" then you should find .minecraft there. If it isn't there, then you somehow messed up the Minecraft installation.
