My assumption is that you are using PHP 7.4. Dat version does not support curly braces syntax. See this answer on stackexchange https://stackoverflow.com/questions/59158548/array-and-string-offset-access-syntax-with-curly-braces-is-deprecated . A downgrade to PHP 7.3 will help. That is also the highest supported version, see https://docs.civicrm.org/installation/en/latest/general/requirements/ .
Another option is to fix the issue and create a patch for it. A remark on the https://lab.civicrm.org/dev/core/-/issues/1496 will also help.
