Admin UI (settings) has critical PHP error

Hi,

when i open in my multisite’s subsite the settings (admin) page of “Network Posts Extended” plugin, I get following error in my Apache error log and page crash.

[Fri Apr 19 05:30:08.974202 2024] [php:error] [pid 39699] [client 87.92.171.122:61928] PHP Fatal error:?

Some information about my WordPress:

• Multisite (uni321.com), the issue happens at uni321.com/demo subsite
• Latest WordPress version 6.5.2
• I have protected the filesystem (plugins do not have write permission to directories, except uploads) and I use FTPS updates

So, I cannot use the plugin. Any idea when this bug would be fixed?
