Custom Record Field Error: java.lang.RuntimeException: tvJavaBridge is null

Our tenant is currently on Appian cloud version 24.2 and experiencing a real-time aggregation error on a custom record field. When editing the custom record field in the record type view, clicking the 'TEST' button displays the following error: ava.lang.RuntimeException: tvJavaBridge is null

We have tried removing the relationship and re-adding to no avail. Also, testing the rule in an expression also yields the same result (see screenshots below). Any ideas of what we could try to alleviate the issue?
