I can confirm the issue.

I can also confirm. It happens on other custom fieldtypes too, like StreetAddress. I replaced $fieldtypes->prepend($fieldtype); with if($fieldtypes) $fieldtypes->prepend($fieldtype); but then I get PHP Warning: count(): Parameter must be an array or an object that implements Countable in ...\Process\ProcessField\ProcessField.module:1414, and fixed that with wireCount(). Not sure if I'm on the right track...

Maybe change this line to:

$fieldtypes = $fieldtype->getCompatibleFieldtypes($field) ?: $this->wire(new Fieldtypes());
