Pika Backup failing to open archive

I’m trying to open a backup archive on which is on a USB mounted drive (also separately on the same disk to test) and am getting this error

According to this issue it may be a Bluefin thing but I’m not sure.

I’m on Pika Backup v0.7.4.
bootc status:

Pika also has the default permissions.

Is anyone else experiencing this problem?

Did you by any chance remove a permission(s) for Pika in Flatseal? I think I had this happen once in the past, but reverting the permission back solved it for me.

@Lethe, thank you for your message.
Permissions are as is. I also did a reset of the permissions in Flatseal and there was unfortunately no difference.
