Also, you need to have had the respective block at least once in your inventory to unlock the respective trapdoor recipe (e.g. collect oak planks to unlock the oak trapdoor recipe).
The Vanilla Tweaks 'More Trapdoors' datapack could be causing this issue as 1.20.[5-6] introduced breaking changes to datapacks, so that old ones do not work anymore.
