[Bug] Crash when pressing connect with no info

[ElDavoo]

Describe the bug
When you press "connect" without saved devices or infos (ip address and password), the program will load for many seconds and then crash.

To Reproduce
Steps to reproduce the behavior:

1. Install app
2. Click connect

Expected behavior
I expected basic form validation (a message like "ip is empty, password is empty")

Desktop (please complete the following information):

• OS: Windows 11
• Version 1.0.15.0

Tried with 1.0.16.0

What did you enter to login?

[ElDavoo]

nothing

[furesoft]

hmm. I have tested it without an exception. Did you do anything special?

[ElDavoo]

In Windows Sandbox, this appears on version 1.0.18.0 (minor layout problem)

No, but the error is fixed (even though the text layout is wrong)
