Cannot load the custom probe when it is not already compiled

[avogadro5]

I have a custom probe for my class with "Separate compiled code from source file" checked. When the wire for the class is first probed with a clear compiled object cache, this error shows:

The probe is then replaced with the LabVIEW default representation of the class private data. When the probe is removed and recreated, or created on another wire, the custom probe shows as intended with no error, presumably because its compiled object(s) now exist in the cache.

When the probe VI does not have "Separate compiled code from source file" checked, the probe always works as intended and never pops up an error.

The attached "table.zip" exhibits this error (LabVIEW 2020). "probe.vi" is a member of the class and the class is configured to use it as the default probe.
