I'm gonna actually take the time to debunk this shit, bit by bit:
1. Yiddish probably developed in the Rhine Valley, far away from the Caucasus Mountains and the Caspian Sea that were home to the Khazars. It developed as a Jewish dialect of a local variant of Middle High German.

2. The Khazars, meanwhile, spoke a Turkic language which we assume to have belonged to the Oghur family of Turkic languages. No relation at all to Yiddish.
3. Jews may have issues reaching many agreements, but one thing all observant Jews agree on is that Shabtai Tsvi was a sham and one of the worst people that ever existed, and that Jacob Frank was an evil man.
No Jew venerates them, and no one looks to them for mystical guidance.

Even among Kabbalah practitioners, Tsvi and Frank are used as cautionary tales, and no one learns their teachings.
4. Oh, and finally: not a single Jewish community in the diaspora used Hebrew in everyday use. But all of them used it in liturgical settings, and nearly every halachic or even Kabbalistic text was written in it. No one ever prayed in Yiddish, you muppet.
