SharePoint SE Image Rendering Problem

Hi everyone,

We are currently facing an issue with the image rendering function on SharePoint SE. After migrating our databases from SharePoint 2016 to SharePoint SE, custom renderings are no longer being generated/applied.

We have attempted several troubleshooting steps (without success):

• Clearing the blob cache,
• Resetting the cache block,
• Using a different library (picture/assets),
• Creating new site collections (modern/classic).

The issue is that this problem doesn't occur with all images:

• Some images with high resolutions (3000x5000) are not processing, while others work.
• Some images with a file "weight" of 1.5MB work correctly, while others do not.
• Some images work within one site collection but not in another site collection.

Does anyone have any ideas or has anyone encountered a similar issue?
