SharePoint image column broken

Hello,

On a SharePoint Online List I have 4 image columns that are populated with PowerAutomate
(for details here the tutorial: https://www.youtube.com/watch?v=3QWxVWbwRSM).

Since yesterday almost all images are broken, the link gives this error message in the browser: 

{"error":{"code":"invalidRequest","message":"Invalid request"}}

For one colleague it still works in Edge but not Chrome

I am grateful for help
