UDA file replaced by a partial error message

I recently updated a property description on a document type. Now my UDA file has an update where it's replaced by a stacktrace.

Reproduction

Bug summary

I've created my own simple property editor. The datatype is serialized into a UDA file just fine. The doctype the property is included on was serialized just fine.

After updating the description on the doctype I get a new doctype change like this:

Removing the description and doing a new full uda export via the Deploy dashboard doesn't help so I don't think the description is the underlying cause.

Not really sure where to look or what to do to debug this.

Specifics

Versions: Umbraco 11.2.1 Deploy 11.0.2

Full stacktrace in the deploy file is this - no errors in the deploy log only inside the uda file:

Steps to reproduce

Honestly no idea.

Expected result

It would update the uda file with a description for the property
