I am using git 2.29.2-1 and since ~the last release it happened 2 times that my git user config (user.email and user.name) was suddenly cleared. The rest of the global git config is still correct, so it is no file corruption, it must be a bug in git.

I am not sure if this helps, but this is the history. I am not able to reproduce this reliable.

warning: Pulling without specifying how to reconcile divergent branches is
discouraged. You can squelch this message by running one of the following
commands sometime before your next pull:

git config pull.rebase false # merge (the default strategy)
git config pull.rebase true # rebase
git config pull.ff only # fast-forward only

You can replace "git config" with "git config --global" to set a default
preference for all repositories. You can also pass --rebase, --no-rebase,
or --ff-only on the command line to override the configured default per
invocation.
