Crash with network rule in user filter

[TheHasagi]

Comment:

In filter rule editor simple mode, type any IP like 8.8.8.8$important,network and then press enter, adguard will crash. It is significant that you add important parameter first and then network parameter

This issue is not easy to reproduce. On some machines it not cause a crash, network rule applies successfully.

Logs are available in ncloud.
