Error loading the Customize Theme option (Dawn theme)

Hello everyone, everything good?

Are you having a problem. Every time I click on customize my theme, the following image is displayed (ANNEXED). Does anyone know what I can do?

I use the Dawn Theme and my browser is Microsoft Edge.

I understand what you told me. However, this is the sixth day in a row that the problem has persisted and I have not been able to get a response from Shopify.
