Hi
From the worker log snippet I see that converter is finding two partitions. (Refer to first line).

Please note that Converter Standalone 5.5 cannot convert dynamic disks which have more than one partition regardless of whether both partitions are active or not. Converter Standalone will not be able to convert disks which are multi-boot or have more than one active partitions however this is expected behaviour.
This is a regression which was fixed in Converter Standalone 5.0.1. Hence please try the conversion using Converter Standalone 5.0.1.
If the above solution helps please consider marking this thread as answered.
Alternatively I see a workaround provided in Converter 5.5 release notes for this issue. Please visit below URL and find the section 'Configuration of Windows virtual machines with multiple active partitions might not complete'.
