Images not showing on timeline after update on Premier and macOS

Hi there, I udated recently my mac to Tahoe 26.5, and had issues with premier. I had to delete all the apps and instal them again. Still, when I opened one of my projects, one of the images ‘ image strip with extension tiff’, does not show on the timeline, instead I have a red bar. I already rendered in and out and deleted the files, but it did not solve the issue. Any tip? Many thanks
