Placing any block around a beehive on bedrock will push the bees to spawn behind the block so its impossible to incase them unless you leave a two block space completely around it. I haven't found an effective way to avoid this issue,  Its impossible to farm them when you constantly have to break the blocks to allow the bees to access their hive again. I've been noticing this issue since 1.18 and haven't been able to farm bees since,
