[GAMEBREAKING] Cannot load any worlds due to "errors in selected datapacks"

[Tempest-5ky]

What version are you seeing the problem on?

1.18.2

Describe the issue

1. Download Pollen for Fabric 1.18.2
2. Load minecraft
3. Try to create a world
4. Get error

Initially found issue in a modpack with ~300 mods but I tested with only Pollen and fabric API and got the same issue/error. GAMEBREAKING, completely prevents creation of worlds!
