Having same issues. And tried similar fixes as OP. Seems to be closely tied to Nether Portals as it happens all the time to me in the Nether. Overworld seems to not be as bad but has happened. ALSO I loose progress. Whether it is mining progress. Gathering Progress Building progress etc. It will randomly reset. Worst time it happened was I lost over a hour of play time. Rubber Banded me back to a previous save type point.
No Mods. No addons. Just Plain old MC. Never had cheats or nothing enabled.
