I am using GitKraken as my git client and it was always working fine, but for a few days I am getting the error fatal: bad boolean config value 'null' for 'commit.gpgsign' when I use any other git clients. I have tried cmd, vscode, PowerShell in vscode and Git GUI. I have also uninstalled the GitKraken and try, but I guess it somehow retains the settings. Have you ever experienced this issue?
