Internal Server Error
user error (gpg ["--quiet","--trust-model","always","--with-colons","--list-secret-keys","--fixed-list-mode"] exited 2)

gpg: fatal: can't create directory `/home/Xaver/.gnupg': No such file or directory

makes no sense on windows machine

must be like "C:\Users\Xaver\AppData\Roaming\gnupg" or %Username%\AppData\Roaming\gnupg I guess.

gpg itself works fine I use it with thunderbird
