You're using 64bit python? Can you try the 32bit python or 64bit version of calibre? You need to delete the 64bit python and the 'C:\Users\sam\AppData\Roaming\calibre\plugins\word dumb-numpy1.20.1' folder if you wanna install the 32bit python.
calibre and python should use the same architecture, both 64 or 32.
