I did some more testing today and after enabling / disabling local network for a completely different app, it also temporary fixes the same setting for all other applications. It's like this whole list is somehow not remembered after a reboot.

This issue still appears on macOS Sequoia 15.3 To give some more details: I am using OrbStack on a Mac Mini M4 and mounting an NFS Volume with it from my local network. It all works perfectly fine until I do a reboot. Then it seems like it didn't remember the setting at all. When I go into Privacy & Security -> Local Network and untoggle + toggle the checkbox near OrbStack then everything works fine again. It's a very nice privacy feature, but frustrating that it doesn't work properly after a reboot.
