ERROR: Data Connection: [json.exception.type_error.316] invalid UTF-8 byte at index 1: 0xF2 (Windows 11 / Nexus Core 3.1.5)

Problem description:

When running Nexus Core 3.1.5 on my Windows 11 Home Edition (Chinese version), I encountered the following error in the logs:

[18:46:46.221] ERROR: Thread : Data Connection: [json.exception.type_error.316] invalid UTF-8 byte at index 1: 0xF2

The wallet fails to synchronize properly, and I am also seeing a very large number of "ORPHAN height=..." log lines.

What I have tried:

• Connecting only to the official node: connect=node1.nexus.io
• Deleting peers.dat and cache files in the data directory
• Saving nexus.conf as UTF-8
• Running on a different network (VPN and no VPN)
• Ensured Windows Defender firewall allows Nexus Core and relevant ports

My setup:

• OS: Windows 11 Home Edition (Chinese version)
• Nexus Core Version: 3.1.5 (official wallet)
• Wallet build date: December 11th, 2024
• Core build date: December 6th, 2024
• VPN/Proxy: Tested with and without VPN
• Network environment: Home WiFi in Italy
• Only using official node (no third-party nodes)

nexus.conf content:

Relevant log lines:
(I have attached my 0.log file for detailed logs.)

[19:30:22.779] Process : ORPHAN height=351406 prev=...
... (many similar ORPHAN log lines) ...

Additional notes:

I am not running any other blockchain node or third-party apps at the same time.

My system language is Chinese—could this affect JSON decoding or data connection?

Wallet About information screenshot attached.

Please let me know if more detailed logs or other info is needed.
