The bug
I found a naturally generated bee nest with 2 bees and everything look right, until they entered the nest, they can't go out of it. they exit the hive for a split second then they go back.
I also placed lots and lots of bee nests in creative mode and after a while, no bees wandering, just split second glimpses of they trying to get out. They spawn outside the bee nest and enter it again, after some time I managed to screenshot a split second bee, the image is attached (look how there are lots of nests and no bees. also look at the sound transcription, every second or so some bee fail to escape).
Even with campfires underneath the bees won't go out.
My theory is that, a bee can enter a bee nest, exit it, enter again, and then is stuck. in other words, they can exit the bee nest only once.

Confirmed, at least for bees that exit the nest after nighttime.
Edit: Also just confirmed for bees at any time. This glitch is probably caused because bees can now enter their nests without being "pollinated", causing an infinite loop of bees not escaping.
Here's a video of the bees popping out and immediately back into the nests: https://www.youtube.com/watch?v=pzkDdvquWWY Hope this is helpful. :3
I can confirm this for at least one of my hives.
In my experiments, bee overpopulation despite lots of hives seemed to be a factor in triggering this issue (but once they had entered this state, culling the other bees to resolve the overpopulation didn't do any good); luring a lot of bees with a flower also may have contributed, but I couldn't identify a clear pattern.
Silk touching an affected hive and placing it somewhere else seemed to have some effect on the situation, in that individual bees would subsequently pop out their heads for more than just a tick before returning, and one even got "unstuck", but this seems to be neither a reliable nor a permanent cure.
I tried to bring flowers right up to the hive; free delivery of nectar right to your doorstep! The bees weren't going for it though. XD
I made a datapack to see some data from bees and hives.
I want to add to this report that when this bug start to happen, the TicksInHive changes from 2400 to 600. Maybe the bug is in the hive block and not in the bees

I saw the same issue after updating a 19w44a world to 19w45a. Every few seconds bees in my nests exit briefly and disappear into the next again.
