Thank you for your answer.
I’m not a developer, and I don’t know how to generate the logcat.
I understand that you have the same bug, and it also affects other devices, such as FP.
What would you suggest I do to resolve this issue? Should I post it on GitLab, or is it fine here?
In fact, this problem was reported several years ago, but to date it has not been assigned to anyone. So I guess it’s not something to be prioritized for now.
In my case, all my photos are stored on the SD card folder, which makes the app totally unusable.
But as mentioned above, this is not an insurmountable problem, as there are plenty of similar applications. For instance, “Fossify Gallery” works pretty well.
