Notes on iCloud inaccessible in Sonoma

I have a MacBook Pro 2018, 6 core 2.6ghz intel i7core chip, with Vega 16 4GB RAM GPU and 32GB DDR4 RAM running Sonoma 14.7.1. After upgrading to Sonoma, iCloud will not open my notes. I get the following mesag: "Notes for iCloud cannot open. This browser [Safari Version 17.6 (19618.3.11.11.5)] WebGL feature is not available.Try restarting the browser or try a different browser.

That sounds ridiculous- Apple own browser cannot open apples own app...ideas?
