Sure! Thanks for helping.
1. Start:
git bisect start
git bisect good <commit hash or tag name of the version that works> (Ex:
v1.7.1)
git bisect bad <commit hash or tag name of the non working version> (Ex:
HEAD)
2. Git will checkout commits for you and you have to check and answer:
git bisect good or git bisect bad
3. Git will show you the first bad commit.
A more detailed version here:

Look for git-bisect.
Thanks,
Marcel
