We know black holes disappear without any trace of information,  could it be possible that fabric of space level it self, after blackhole  warps it so much it stops affecting event horizon. leaving a black hole sunk into closed bubble of the universe.

Black holes don't disappear.(*)

But the second part is a reasonable description of a black hole: the inside is effectively sealed off from the rest of the universe. The event horizon is like a boundary between this universe and the bubble inside the black hole.

 

(*) If Hawking radiation exists then really tiny black holes would evaporate but we don't have nay evidence that such tiny black holes can be created. (And we don't know fr sure that Hawking radiation actually happens.)

Ahh, thanks, I may have watched wrong youtube video. This theory looked interesting as it would also solve dark matter, as this unknown gravity could be remnant of the ancient black holes that has been patched up and no longer visible, while still curving the space without breaking it up

Well, one possible explanation for (some) dark matter would be if there were a large number of small black holes around (they would, as you say, be invisible). Attempts to detect them (by looking for gravitational lensing) has not shown any evidence. So if they are there, there are not many of them.
