Upgrading an Angular app from @okta/okta-auth-js 6.2.0 to 6.4.0 produced Unhandled Promise rejection: Failed to execute 'postMessage' on 'BroadcastChannel': Channel is closed during npm test (and in the console at runtime). The SDK's cross-tab communication channel was being used after it was closed. Nothing in the app had changed besides the SDK version bump, which pointed at the 6.4.0 release itself.

Fixed in @okta/okta-auth-js 6.7.0; the reporter confirmed upgrading to 6.7.0 removed the BroadcastChannel errors. Upgrade past 6.7. The Okta team also recommends reading tokens from the tokenManager directly rather than authState, as they observed related token staleness issues around the same upgrade.
