It makes debugserver doesn't work

[nffly]

Environment:
iphone7
ios 15.4
jailbreak with palera1n

ssl-kill-switch3 used:
moe.misty.sslkillswitch3_1.5.1+rootful_iphoneos-arm.deb
moe.misty.sslkillswitch3_1.4+rootful_iphoneos-arm.deb

Problem:
once install ssl-kill-switch3, the debugserver will exit immediately, Whether it is started through Xcode or manually.
and debugserver will always output a string of strange characters (if started by xcode,it will output this string too).

xxx:/Developer/usr/bin root# ./debugserver --version

debugserver-@(#)PROGRAM:LLDB  PROJECT:lldb-1316.2.4.16
 for arm64.

After many test and I'm sure it's ssl-kill-switch3 that's causing the problem. As long as ssl-kill-switch3 is uninstalled, there will be no problem. for now, 1.4 1.5.1 can cause this problem.
By the way, ssl-kill-switch2 does't cause this problem.

Looking forward to your help. Thanks!
