The bug
(helper note: added from silentwisperer's comment)
There are actually a variety of bugs with withers when it comes to unloading them, dying and unloading the wither is what causes this invisible/immortal bug to happen.
To reproduce:
1. Create a normal world, hard, cheats on, simulation distance 4, and whatever else you like.
2. Lower your render distance as much as you can.
3. From world spawn go about 200 blocks past the furthest thing you can see from spawn
(we want the wither to be completely unloaded, out of render distance even)
4. Once you have found a location, spawn a wither and damage it to just over half health.
5. Once the wither is slightly above half health, do `/kill @s`
6. Slowly fly back to where you summoned the wither, and you will see it have the summon animation again. Hitting it a couple times should cause it to "die" but not play the actual death animation. After this, if done correctly you should have an invisible immortal wither.
7. Summon some chickens around to have the wither target them to prove it exists.
Optional: Set an always active repeating command to do `tp @e[type=wither] ~ ~3 ~`
and you can attempt to kill the wither using what ever means you like, its truly immortal.
Original description
unable to beat the wither as he turns into invisible and the status bar despairs.

I don't have no resources packs or add ons applied and it happen in every world, including newly ones.
i hope this answers your questions.
Could you upload a video of the bug occurring, and add steps to reproduce the issue? Could you also check that the difficulty is set to Easy or higher?
I'm actually suffering from this same issue. I'm running a world on a Realm, we just spawned in the Wither, the fight was able to go okay for maybe 5 minutes and then the health bar vanished but the Wither was still visible. After knocking the Wither down to the second stage where it killed me for the last time before the bug happened the Wither literally vanished but continued to hurl Wither skulls at anyone within range.
Every time anyone returned to where we spawned the Wither we were able to see the Wither in a pure white skin as it hurled Wither skulls at us. We were able to watch said Wither appear to "die" or "despawn" and from that point on Wither skulls would be hurled from an invisible enemy. Every time we died it would put in a death message that we either withered away or were blown up by the Wither. All of our gear also vanished after the first death from the period when the Wither had gone into its second stage–even though it took ten seconds to return to the spot where we died and the moment the Wither glitched.
Also discovered the day/night/weather cycle broken in synchronous with the Wither resulting in day/night/weather cycle still appearing to work visually, but no effect on the world as a whole. Mobs would spawn as if night and would not suffer damage even if the game visible showed day.
Only packs loaded in are a texture pack, Chroma Hills HD. Nothing else added, no cheats allowed, pure 100% survival world because we as friends wanted to get achievements together.
It looks like there are several issues at play here:
MCPE-32415 The Wither shows white spawning animation when you move away and back again
MCPE-39205 Phantoms do not burn during the day when the sky is darkened by the Wither
MCPE-41002 Dropped inventory despawns on death on Realms
As those have already been reported, it would be greatly appreciated if you could add a vote and any new information to those tickets.
The extra issue that this ticket mentions are related to the Wither health bar disappearing, and that the Wither will turn invisible.
Does the issue with the wither turning invisible only happen on Realms, or can it happen in a local single-player world with just the vanilla textures?
Confirmed. Used the long tunnel method, the wither did not follow me so I had to brave being exposed to it, it killed me then when I went back to it the health bar disappeared. Hopefully when I go back I will be able to fight it properly or I will lose hours of hard work that I've put into my world, not good.
Basically on Hard Mode the Wither is impossible to kill on single player unless you have a bunch of totems of undying which I find kinda stupid because it means it's WAY too hard. Even with full blast prot, you can't even get near him without using at least 2 totems of undying (which can be pretty rare unless you build a raid farm).
@unknown: Your video doesn't appear to show the same bug as this report describes. Your video shows the health bar disappear, but the wither is still visible and in fact is not far away. In addition, this bug was closed 8 months ago as "Fixed" and that status wasn't challenged by any of the dozens of players who were experiencing it, until now. Therefore, it's very likely that this bug was actually fixed and the one you're reporting is something different.
Please search for a report that is still open and that describes your issue more closely. If you can't find one, feel free to create a new report for your issue. Be sure to attach your video (it suggests to me that the wither's health bar disappeared when you opened your inventory, which might be a very helpful clue), but please also describe the issue carefully in words. When you only provide a video, we can't tell which events in it seem significant to you.
Do you have any resource packs or add ons applied? Does this happen in every world, including newly made ones?
