问题开始于我无法签署我的Git提交。

$ git commit --verbose -S -sam "Attempt to sign commit"

gpg: invalid size of lockfile 'C:\Users\username\.gnupg/gnupg_spawn_agent_sentinel.lock'
gpg: cannot read lockfile
gpg: can't connect to the agent: Invalid argument
gpg: keydb_search failed: No agent running
gpg: skipped "KEY_ID_ABC123": No agent running
gpg: signing failed: No agent running
error: gpg failed to sign the data
fatal: failed to write commit object

我似乎无法签名，因为GPG代理没有运行，而代理没有运行是因为gnupg_spawn_agent_sentinel.lock的锁定文件大小无效。
运行gpg -K也会出现类似的错误：

$ gpg -K

gpg: invalid size of lockfile 'C:\Users\username\.gnupg/gnupg_spawn_agent_sentinel.lock'
gpg: cannot read lockfile
gpg: can't connect to the agent: Invalid argument

我检查了~/.gnupg/gnupg_spawn_agent_sentinel.lock的文件大小

$ ll ~/.gnupg/ | grep gnupg_spawn_agent_sentinel

-rw-r--r-- 1 username 1049089     0 Dec 16 16:53 gnupg_spawn_agent_sentinel.lock

它显示gnupg_spawn_agent_sentinel.lock是0字节！回家了吗？我该如何从这里继续解决这个错误呢？
