ReviewX website fatal error php 8.1.0

After updating to the latest version 2.0.0 ReviewX has started giving a fatal error for the my website. Error message says it could either be an issue with php v8.1.0 or a cause “generic fatal error”

I am not receiving an error to our wclogs file. Is there a new php version requirement for the latest version? If so would it be possible to roll back to the last version until we can update our servers.
