I've been using CK Dashboard for several years to maintain updates that propagate to user apps. Recently I have had a problem adding or updating any record that has an asset in it. Adding the asset seems to go fine until I hit the "Save" button. Then it comes back with "! Load Failed". This happens every time. I'm using the latest build of Safari in Big Sur 11.6.1. I have searched preferences to see if somehow Safari does not have access permissions, but it does not matter what directory the uploaded file resides in - it fails every time. I can download a record with an asset, but if I change the asset and save, it fails. Saving from a live app in iOS continues to work fine. This seems to be some sort of permission issue, but I am the only user and I have all permissions enabled. Logging out/back in has no effect. This problem exists in both my M1 iMac and M1 MacBook Air (Monterey). Looking for anyone else having the problem before filing a bug.
