Same as this issue https://github.com/NanoVNA-Saver/nanovna-saver/issues/460 probably. It was opened after yours, and got more response, I feel for you ~

Long story short,

• either deactivate setting "Validate received data" in device "Manage" menu
• or do a full calibration OPEN+SHORT+LOAD+ISOLN+TRHU of our nanoVNA in directly on the device.
