More info about the issue:

The issue comes from https://github.com/jenkinsci/email-ext-plugin/blob/06a409c9078bc12785ae1661cf3d8e50d7b34579/src/main/java/hudson/plugins/emailext/ExtendedEmailPublisherDescriptor.java#L711

which is called when saving the System Config page and then it is calling the method create() in ApprovalContext https://github.com/jenkinsci/script-security-plugin/blob/ecf66020eb7d5960a576cb0d3ffd0180de62a518/src/main/java/org/jenkinsci/plugins/scriptsecurity/scripts/ApprovalContext.java#L55

Therefore, when disabling the email-ext plugin, the issue is no longer reproduced.
