Sorting on SharePoint List attachments doesn't work anymore

I have a PowerApp form for my SharePoint list that also contains attachments. I set the Attachments control to sort in a descending order, but when I click the attachment to open it, I get a 'BlobNotFound' error in Chrome and a 'Couldn't download the file' error in Internet Explorer.

When I create a new PowerApp form, the default Attachments control lets me download attachments, but immediately after I apply the Sort() on the Items property, the 'BlobNotFound' error appears again.

Sort(
 ThisItem.'{Attachments}',
 DisplayName,
 Descending
)

This has worked before flawelessly, so why doesn't it work anymore?

I'm not sure what your doing to pull in the Attachments exactly but typically when I have a gallery with the attachments the item was first selected from another gallery and so that is there instead of the ThisItem you have.

So, Gallery 1 is tied to the SPList and has some details of some sort and then when they click on one Gallery 2 shows with the attacments.

My Items for Gallery 2 is =Sort(Gallery1.Selected.'{Attachments}', DisplayName, Descending)

Mine sorts fine and pulls in the data fine, allows you to download and everything else. Maybe try that.

I'm just using a simple form (using the Customize Forms option in SharePoint). I don't use a Gallery.
The solution I used worked 2 weeks ago, but now, all of a sudden it doesn't anymore even though I haven't made any changes to that specific Form...
