this problem is due to React 18 failing when mutating props. In React < 18, it only failed in dev mode, with 18 it also fails in production.

I had the same problem with my lib. The easy fix is to wrap the mutation in a try catch block.

Those are the lines that lead to the error:

child.props.content = `script-src 'strict-dynamic' ${cspHashOf(nextJsSPA)} ${NextStrictCSP.inlineJsHashed.join(' ')} 'unsafe-inline' http: https:;`;
child.props.slug = __NEXT_DATA__.page;

from next-strict-csp.
