Steps to reproduce
Using a verison of Minecraft that included the crouch and crawl experiment, create a world with only that experiment enabled.
Transfer the world to the current version of Minecraft.
Open the world, then check the world settings menu.
Expected results
No experiments enabled.
Observed results
All experiments enabled.
During the development of the crouch and crawl features, I included this experimental feature in my world. After the full version of this feature was released, the world remained experimental and included Molang, Holiday, and Upcoming Creator Features. I didn't enable these experiments, I don't need them, and there is no way to disable them.

What do you mean by "the world breaks"? Having these options on does not necessarily "break" the world.
What specific device(s) did you encounter this on? Please do not choose Multiple without providing that information.
Are you able to replicate this issue with a newly created world? If so, please provide steps to do so.

Having these features include changes to the world unwanted by the player. How can I replicate this if the latest experiments are the villagers, and those obviously won't be the soonest innovation?
Step 1: Enable the desired experiment in the created world
Step 2: Wait for the full release of the experimental function to disappear
Step 3: Enjoy the non-disabled features.
I updated the summary to reflect what I think you are describing. Let us know if that is not what you mean.
I apologize for the delay. Also, I'm sure that these bugs have one source - when after beta version the world is launched from the regular version - Beta APIs are enabled. Β Also you have a file size limit here so I had to upload the world to google drive, I had no other choice. https://drive.google.com/file/d/1qmU9OKIxkk2UMPa-BM9Nu92bP52NnAzb/view?usp=sharing
Can you attach/upload a backup of the world where the settings are not broken yet and the experimental crouch remains as the only experiment?
Do you remember what last beta version you were on before you exported and moved to retail?
