I added a png file to the media section by dragging and dropping it onto the media section. When I set this as an image in the image component, the connected companion crashes. The app only contains the image component, so I don't think any other part is affecting this.
Note that when I do the same process but by using the upload button and not drag and drop, the companion doesn't crash.
According to the PR of this feature, it is noted that dragging in multiple files at the same time generates an exception. But it's not mentioned if this happens for a single upload too.
I tested this on two different devices, so it doesn't particularly appear to be a device issue.
