I have also reported this issue now to Cloudways since they control the integration of the Object Cache Pro plugin... (and we cannot roll back to an older version of Object Cache Pro)
@ScottN Maybe you could as well. The more people that report it the more it will most likely get fixed (since at this time it does look like the Object Cache Pro plugin is the issue and not necessarily Metabox).
Even if you've updated Meta Box AIO to the newest version 1.23.0, which does have those file changes, this still doesn't work UNTIL Cloudways updates the MU-PLUGIN Object Cache Pro from 1.19.0 to 1.20.0.
In Object Cache Pro's CHANGELOG:
"* Removed split_the_query filter in favor of native WordPress 6.4 behavior"
