New PHP Fatal Error in Log Report Related to WPFC

I noticed a flood of PHP fatal errors in my log reports recently which appears to be related to the WPFC plugin. These are new, perhaps after a recent update of the plugin.

Is this a known issue that is impacting other users? Any fix for this? Thanks!

Here is an example of the error:
