scanf APIPA address and subnet mask cause crash./扫描APIPA地址和子网掩码导致程序崩溃

[AHLLX]

Describe your issue: I'm using Win11 with msi to install NWM directly, and using the IP scanner to scan the APIPA address with the subnet mask attached causes the program to crash.

我使用Win11用msi直装NWM，使用IP扫描器扫描APIPA地址附加子网掩码就会导致程序崩溃。

NETworkManager version: Version：2024.6.15.0

Windows version (like 10.0.x.x): Win11 prof 22635.2915

.NET version (like 6.0.x): 8.0.1

Can you send me the crash report from %LocalAppData%\NETworkManager\NETworkManager.log (or in the eventlog > Applications - if the log file is empty)
