Multisite Auditor Scan Produces Errors

Hi, I manage a WP Multisite that contains a network of 60 child websites and one parent. I would like to conduct a plugin audit, and am finding that the Multisite Auditor plugin throws errors when I run the scan. First, here is what I am running:

WordPress 6.0.1
PHP Version : 7.4.26
Database Version : 8.0.28
Server Software : Apache/2.4.51 (Debian)

The error produced when I run a scan with the Multisite Auditor:

Fatal error: Uncaught Error: [] operator not supported for strings
in /var/www/html/wp-content/plugins/multisite-auditor/admin/index.php on line 190

Call stack:

include_once()
wp-content/plugins/multisite-auditor/pages.php:172
MSA_pages::drawMSA_overview()
wp-includes/class-wp-hook.php:307
WP_Hook::apply_filters()
wp-includes/class-wp-hook.php:331
WP_Hook::do_action()
wp-includes/plugin.php:476
do_action()
wp-admin/admin.php:259
require_once()
wp-admin/network/admin.php:13

I’m assuming that the issue is probably related to an incompatibility with WP version, seeing as how this plugin’s most recent update was from 5 years ago. Do you know if there are plans to update this plugin?

I see that line 190 in the index.php file being referenced seems to be loading values for $pluginName into the $popularPluginsArray[].

I can see which plugins are being used on each child website under the Sites section of the Multisite Auditor, but am not sure of the accuracy of the list given the error that is taking place above. For instance, one of the child website has 53 active plugins, but the Multisite Auditor only shows 3 plugins being used under the Sites section for that child website.

Please advise.

Thank you!
