Apache 500 error and syntax error in Arr.php

I was just assigned librenms administration after updating php to 7.2. Site worked for a day then we started getting blank pages with the apache 500 error. The error that repeats in the error log is PHP Parse error: syntax error, unexected ‘=’ in /opt/librenms/vendor/laravel/framework/src/Illuminate/Support/Arr.php. Line 388 from that file is [$value, $key] = static::explodePluckParameters($value, $key); The validate output is included below. Any help would be greatly appreciated.
