Issue 100% CPU - WordPress Toolkit PHP processes - Causing downtime

[DataPacket]

It appears the WordPress toolkit is causing 100% CPU by spawning endless PHP processes under sysuser, each consuming 25% CPU. This has caused downtime at least twice for users. It occurs just by clicking on the WordPress link in the admin panel. I tried removing any broken WordPress installations, but did not resolve. For now I had to disable the extension. Any fix?

This is a Windows 2019 server.
