UI issues with Freestyle classic pipeline after Jenkins upgrade to 2.452.3

Contributing UX SIG

Hello,

We have recently upgraded to Jenkins version 2.452.3.

After the upgrade we are not able to save and do any kind of update on Classic FreeStyle pipeline.

Below is the error → " Error

JSONObject[“scm”] is not a JSONObject."

In the UI also all the checkboxs are checked and SCM one’s are not even selectable.
I think that might be causing the issue.

Attaching error screenshots for the reference.

Any help would be appreciated. Let us know how can we fix this quickly.
