Sage.cre.coreproxy has stopped working

SUGGESTED

Hello

While running a WC report I got this error "Sage.CRE.CoreProxy has stopped working" .  I am on version 20.4.1. 

Can anyone tell me what is error is and how to stop it.  Once I receive this error, Sage think the WC window is open and will not let me exit Sage.  I had re-start my computer to exit Sage.
