Uploading image throws exception, C:\temp is writable

[enpa]

• I have enabled debug mode
• I have read checked the Common Issues page

Describe the bug
When uploading a picture to an asset, the picture is displayed as thumbnail near the upload button. Saving leads to an exception ("Image source not readable" in AbstractDecoder.php line 346). Permissions to c:\temp are set as requested.

Intersrtingly, if I uploade the image to the asset as file, there is no issue:

To Reproduce
Steps to reproduce the behavior:

1. Open an asset without picture
2. Click on edit
3. Upload a picture
4. Click save

Screenshots
Picture uploaded, thumbnail shown, looks ok. After clicking on "Save" exception is thrown.
