Global Git Config is ignored after Windows update

[Brice]

Hello. After upgrading from Win10 1709 to 1909 my SourceTree installation neither honors nor can reach the global .gitconfig. Thus, when committing, SourceTree uses my Windows user name as well as associated e-mail address, which are both different from the configured name and address in .gitconfig.

Furthermore, even though the setting to allow SourceTree to edit the global .gitconfig is indeed checked, SourceTree does not modify the file when I change name or address in the settings. It looks like it completely ignores the file.

This occurs for both system and embedded binaries. However if I commit manually from the terminal, or if I uncheck "use global settings" in a repo, then the correct information is used.

How can I fix this behaviour?

EDIT: I of course uninstalled/cleared all AppData folders/reinstalled, to no avail.

I moved the user config ([user], user.name, user.email) to the system gitconfig (in C:\Users\<user>\AppData\Local\Atlassian\SourceTree\git_local\etc) and now it works. Figures!
