Parse error on installation

Problem/Motivation

After installing in a relatively new version of 10.0.7, I got this error:

ParseError: syntax error, unexpected identifier "menu", expecting "]" in Drupal\Core\Extension\Extension->load() (line 1570 of /var/www/html/ed/web/themes/contrib/moksu/moksu.theme).

OpenAI offers this interpretation:

This error indicates that there is a syntax error in the code of the moksu theme. Specifically, there is an unexpected identifier "menu" where a "]" is expected. To fix this, you will need to open the moksu.theme file and find the line of code where the error is occurring. Once you have located the line, you can inspect the code to determine what is causing the syntax error and make the necessary changes to fix it.
