Restored picture edited and developed by Affinity Photo too dark

[HenkF]

Affinity Photo (1.8.3) after developing and editing a RAW (Olympus ORF) file is restored too dark. The saved PNG file by Affinity Photo is ok. See attached example.

Please provide a solution. Thanks in Advance.

Dear Gabe,

1. I am using the latest release version - 1.8.3
2. I can reproduce it. It happens with all edited pictures.
3. With new documents it is no problem, since I don't open them from Apple Photo plug-in. 
4. See enclosed files in my earlier post.

•    My operating system and version: OSX Catalina 10.15.4 ( I use Olympus ORF RAW files)
•    What happened for you (and what you expected to happen): that the photo I worked on in Affinity Photo would look the same when I saved the edited photo back to Apple Photo
•    Provide a recipe for creating the problem (step-by-step what you did): I used normal procedure: in Apple photo I opened the Affinity Photo plug-in, edited in Affinity Photo and closed the edited photo in Affinity Photo, back to Apple Photo to save changes.
•    Screenshots (very handy) or a screen capture/video.
•    Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers: no
•    Did this same thing used to work and if so have you changed anything recently? (software or hardware): Affinity Photo worked in the past, but since a few months it is very unpredictable with the Apple Photo plug-in. Most of the time (90%) the edited photo's in Affinity Photo can not be saved in Apple Photo again.

Thanks. I logged this with our developers.

Update: As a workaround, in Affinity Photo you can set the Assistant Options > Develop Assistant > RAW output format: 16bit
