[schen-fn]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

utils

Version

5.11.1

Current Behavior

I'm using a frozen schema via Object.freeze(). With the latest release my unit tests are failing. I'm getting this error:

TypeError: Cannot assign to read only property 'payment_type' of object '#<Object>'
      at node_modules/@rjsf/utils/src/schema/retrieveSchema.ts:216:43

Expected Behavior

I expect to not get any errors with a patch release

Steps To Reproduce

1. have a schema use oneOf with refs in it
2. freeze this schema using Object.freeze()
3. call retrieveSchema with it

Environment

- OS: macOS Ventura 13.4
- Node: v18.17.0
- npm: 9.6.7

Anything else?
