I can only assume from your response that you haven’t knowingly updated to 2.65 recently. Can you share a screenshot of your update settings for the Triton by visiting Roon Settings → About, and adjacent to the Triton, click on the gear icon.
However, it looks like the Triton OS may need an update, and I recommend that you reach out to them, share this Release Note, and ask them if they continue to support Roon’s minimum requirements.
