Search Operations Fail on the Macbook Pro Calendar App Running Ventura 14.4.1

Macbook M1-Pro/2021 Calendar App search conducted under Ventura 14.4.1 fail for relatively recent Event entries. I've tried disabling then re-enabling the Calendar App from iCloud in the system settings, which fixes the problem for a short period of time. However, after a few hours the searches start failing again.
