NGINX 404 error

Problem/Motivation

We've installed the module with out Azure AD, but the entire Drupal site is showing a 404 error. How do we fix the set up? We're on a Linux Azure web app. We've implemented in nginx.conf under location add: try_files $uri $uri/ /index.php?$args; already to resolve the previous 404 error in this hosting environment and added to the startup.sh. It was working fine until we installed this module and now it's broken again. Any configuration changes to fix?

This is the error log we get:
NOTICE: PHP message: ParseError: syntax error, unexpected token "&" in /home/site/wwwroot/modules/contrib/openid_connect/openid_connect.module on line 91 #0 /home/site/wwwroot/core/lib/Drupal/Core/Extension/ModuleHandler.php(128): Drupal\Core\Extension\Extension->load()
