Open new SMB Connection crashes

[i-r-raccoon]

Describe the bug Tried to open up a SMB connection, but crash happens when clicking on the option.

I'm on grapheneOS, where permissons might be stricter. If testes it with all availabe permissions enabled though, which would be 'Network', 'Notifications', 'Sensors'.

To Reproduce Steps to reproduce the behavior:

1. Click on '+'
2. Click on 'Cloud Connection'
3. Select 'SMB Connection'
4. See crash log

Seems this is not related to hardened Androids - more like a general for newer Androids, as read from here

https://github.com/resourcepool/ssdp-client/issues/28

Let's see if adding a check at NetworkUtil.getLocalInetAddress() would help.

Still crashing on the latest version, unfortunately couldn't find a work-around. GrapheneOS as well , Pixel 8, latest version.

Edit: Moved to Material Files instead since I don't feel like building from source.
