Hi,
Welcome to the community!
Your version is past EOL. You should upgrade to either the latest version or the current LTA (long-term active version) at your earliest convenience. Your upgrade path is:
10.3 → 2025.1.3 → 2025.3.1 (last step optional)
You may find these resources helpful:
If you have questions about upgrading, feel free to open a new thread for that here.
If your error persists after upgrade, please come back to us.
Thx,
Ann
