Comment (by poena):

 Hi!
 Can you provide any more information about how to reproduce this issue?
 For example, does your website use the Duotone feature, and in what way,
 and is the feature working beside this notice?

 You mentioned that you disabled all plugins, which makes me think the
 issue may be with your theme. Are you able to test with a bundled theme
 (such as Twenty Twenty, Twenty Twenty-Three)?

 I can see the visible errors when visiting your website, if you are unsure
 of how to hide these messages from visitors, please see
