Witch hut doesn't spawn anymore

After the 1.18 release, I noticed that swamp biome generates less frequently when loading up a new world. But that is not the problem here, the problem is that witch hut doesn't spawn anymore. I tried searching it using chunk base witch hut finder but when I try to go to a witch hut spawn coordinate, it seems that no witch hut structure is generated. Tried it multiple times kn different locations but it seems witch hut doesn't generate anymore. I hope devs will fix this in a hotfix update or 1.19 releases. I also hope that devs will consider to increase swamp biome generation on 1.19.
