(base) PS E:\vscodeProject\chz8bit.github.io\quickstart> git submodule add https://github.com/nanxiaobei/hugo-paper themes/paper
Cloning into 'E:/vscodeProject/chz8bit.github.io/quickstart/themes/paper'...
fatal: unable to access 'https://github.com/nanxiaobei/hugo-paper/': SSL certificate problem: unable to get local issuer certificate
fatal: clone of 'https://github.com/nanxiaobei/hugo-paper' into submodule path 'E:/vscodeProject/chz8bit.github.io/quickstart/themes/paper' failed

Solved the problem with the following link
How do I configure Git to trust certificates from the Windows Certificate Store? – Stack Overflow
Cant clone from GitHub : SSL certificate problem: unable to get local issuer certificate Issue #9293 desktop/desktop
Personally, I think it is mainly this line of code, and there is a corresponding explanation https://github.com/desktop/desktop/issues/9293#issuecomment-607357181

git config --global http.sslBackend schannel
