photo turns totally black after editing

[pwepwe973]

Describe the bug After doing the editing, I click on save and the saved photo is totally black, all the pixels of the photo become black

To Reproduce Steps to reproduce the behavior:

1. open photo in nextcloud
2. click on the edit pencil at the top right 3.retouch the photos (saturation, luminosity, etc.)
3. click save
4. the photos saved in the cloud has now become a totally black image

Expected behavior that my photos be saved with the same image before retouching but with more beauty more saturation and light but not a totally black image luckily I always make backups
