GTNXi stutter

[jetsep]

Unfortunately we are back to stutters as described in my initial post.
This time I took time to investigate deeper.
Stutter happening with any plane using the TDS GPS.
If I kill the related running task in the task manager (TDS...gps...) everything is back to smooth. This imply that the rest of the configuration in the PC is ok. Loading and using any plane that does not use TDS gps will not show any stuttering during flight. This behavior is consistent and can be replicated anytime.
Within the document folder, both units txt.log file read similar and are reporting an error in writing a file:
