These blocks **will crash** the project when I click the button:

These **will not crash** :

So there appears to be a bug that is causing shuffled list variables to crash.

Hello @tatiang  
Thank you for sharing it.  
I created a testing project and I added the blocks you had but I couldn’t replicate the issue.  
Could you please check [this project](https://x.thunkable.com/projects/64c13682f9c7fb7140b88c2a/30e40bc8-87a6-4ffa-96aa-1cd1351dc884/settings)?
