Cannot save with Affinity Photo

[Earthling]

Since the update to 1.9.0 and 1.9.1 I cannot save any file (existing or new) on any location (local disc, smb-network, afp-network, USB-drive): see error message in the second image
I removed the application, including all data found in ~/Library/Application Support/ , ~/Library/Application Scripts/ , ~/Library/Containers/ , ~/Library/Group Containers/ : see list in the image
I reinstalled (from App Store) -> same effect
Using another User, saving works just fine.

Where does the application save (temporary?) its files?
Is there any configuration I missed?

Any support is highly appreciated, Affinity photo is one of my most used application!
Best, Earthling

Welcome to the forums @Earthling It does seem to be user account specific in some way, as the other user account saves without issue. You can try repairing your disk permissions, which may resolve the issue, see this link for more information.
