**Solution**
The attachment is a zip archive with this directory structure:
git/
.git/
...
HelloWorld.txt
There is no stash nor commits in the log, and the `develop` branch seems to be the same. But, using `git reflog`:
22d3349 HEAD@{0}: checkout: moving from develop to master
22d3349 HEAD@{1}: rebase -i (finish): returning to refs/heads/develop
22d3349 HEAD@{2}: rebase -i (start): checkout 22d3349
f671986 HEAD@{3}: checkout: moving from master to develop
22d3349 HEAD@{4}: checkout: moving from develop to master
f671986 HEAD@{5}: checkout: moving from master to develop
22d3349 HEAD@{6}: checkout: moving from rctf to master
f671986 HEAD@{7}: commit: Revert
f4d0f6d HEAD@{8}: commit: Flag
22d3349 HEAD@{9}: checkout: moving from master to rctf
22d3349 HEAD@{10}: commit (initial): Initial Commit
We see there was a `Flag` commit that was reverted. So we can `git checkout f4d0f6d` which reveals the `flag.txt` file.
`RCTF{gIt_BranCh_aNd_l0g}`
