Cannot commit with GPG sign

Question

I've done all steps here:
https://confluence.atlassian.com/bitbucketserver074/using-gpg-keys-1019385721.html?utm_campaign=in-app-help&utm_medium=in-app-help&utm_source=stash
But when I try to commit, not successfully:

git commit -S -m your commit message

An error occurs:
$ git commit -S -m "Test"
error: cannot spawn C:\Users\abc\.gnupg: Permission denied
error: gpg failed to sign the data
fatal: failed to write commit object

I am able to delete/edit folder/files but Source tree cannot access.
Config file look like that:

[commit]
         signingkey = xxxxxxxxxxxxxxxxxxxxxxxxx
         gpgsign = true
[gpg]
         program = C:\Users\abc\.gnupg

That suggests that the current user does not have full read/write/execute/delete access to the files in the abc direcotory (possibly because of a lack of access to the directory itself)

Check the permissions first.  If you find they look ok, then the next test would be to try to edit the .gnupg file with another application (a text editor probably) as that may tell you more about why it can't access the file.
