Script changes not applied to published activities

Hello, I have made an activity, but I have not set the correct value on each screen. Some students already took the activity. Now when I modify the activity and change the script to check the correctness. It looks like it’s not applied to the published activity.

Is there a way I can edit the script and have it applied to my published activity ?
Thanks for your help

Unless it’s changed with all the updates that have been happening, assigned activities are locked into that version.
