The error disappeared after downgrading PHP from 8.1.5 to 7.3.33. Seems related to issue corrected in Yii captcha-extended extension version 1.0.3 (see https://www.yiiframework.com/extension/captcha-extended#version-103-feb-19-2021)

If the bug was confirmed, LS 5.3 should be considered compatible with PHP versions between 7.2.5 and 7.3.33, and not with any PHP version newer than 7.2.5. Upgrading captcha-extended to latest version extension could resolve the issue
