When "towering up" the game glitches and I bounce after landing thrown from the tower.

Game Version: Bedrock 1.17.11, playing on private Realm.

please note : this was BEFORE (and after) the Hotfix. in other words its not BECAUSE of the hotfix

1) When "towering up" by making a pillar by jumping up and placing a block under my character, randomly/ intermittently but very frequently, the game glitches and I bounce after landing thrown from the tower. Going very slowly seems to make it more "stable" (I get higher before being "bumped" ). Also sometimes when I DON'T fall off I become embedded in whatever block I'm using waist deep. Not a big issue since I can just jump up, but seems as though whatever is causing that may also be the reason I keep getting "bumped" off the tower?

If I see anything else I'll let you know
