It looks like you are using a 3rd party package called "Auto Image Optimizer" which, based on the error, isn't compatible with that version of Umbraco/Image Sharp. As a result you are getting an error occurring.
Tested with Umbraco 13.3 and Dyfort.Umbraco.AutoImageOptimize 2.0.1 and SixLabors.ImageSharp 3.1.3 as part of regular umbraco installaltion looks working without problem
Images not loading
After upgrading to Umbraco v13.3 and ImageSharp to v3.1.4 images are not uploading and opens anymore
Hi Nikita,

I would advise raising the issue with them directly on their website - https://www.dyfort.com/products/umbraco-autoimage-optimize/
Thanks
