 * Upgraded Mailpoet to v5.30.0.
 * As soon as I try and go to the Mailpoet home page in my dashboard I get the below
   stacktrace.
 * WordPress: v7.0
   PHP: v8.5
 *     ```wp-block-code
       File name: No fileName reported Stack trace: ReferenceError: Cannot access 'D' before initialization    at Object.U (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:603147)    at N (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/admin.js?ver=5.30.0:2:6029)    at ha (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2050523)    at vc (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2109457)    at Ml (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2098697)    at hl (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2098625)    at bl (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2098488)    at ol (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2095323)    at rl (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2093879)    at v (https://[my domain]/wp-content/plugins/mailpoet/assets/dist/js/commons.js?ver=5.30.0:2:2190694)

 * Hi [@conorsboyd](https://wordpress.org/support/users/conorsboyd/), I wasn’t able
   to reproduce the issue. Could you please try updating MailPoet to latest version(
   5.31.0 or 5.32.0), to see if that doesn’t fix it? If not, could you please share
   a screenshot of the console error including message before the error?

 * Thanks for the advice.
 * I have updated to v5.32.0 and can no longer reproduce the problem.
