I cannot save config changes for freestyle jobs. I think this started happening after upgrading Jenkins, but hard to be sure about that.

Problem does not affect my jenkinsfile/pipeline jobs.

Clicking the save button does nothing. No save, no error shown, no nothing. Apply does not save either. Does nothing.

Don't know whether it's relevant, but when I open a freestyle job to config I get lots of browser logging:

configure:1 The Cross-Origin-Opener-Policy header has been ignored, because the origin was untrustworthy. It was defined either in the final response or a redirect. Please deliver the response using the HTTPS protocol. You can also use the 'localhost' origin instead. See https://www.w3.org/TR/powerful-features/#potentially-trustworthy-origin and https://html.spec.whatwg.org/#the-cross-origin-opener-policy-header.
