Unable to trace or spawn process

首先，使用 frida 12.0.7 和 frida-server-12.0.7-android-arm64 重现报告中的 frida-ps -Uai、frida-trace、attach-pid 和 spawn 命令。将正常工作的进程列表与 attach 和 spawn 失败的情况进行比较；当可以在不发生超时或设备卡死的情况下对进程执行 attach 和 spawn 时，即表示完成。

Hi everyone !

Great tool, have been working with this for sometime now ( 2 months ).

However before updating to version 12.0.7, I was able to work fine on my lenovo k3 note.
However now, only frida-ps works and nothing else.

I tried using the process name from there to run frida-trace on it but in vain.
Also both the versions are same on the device and on python.
First I installed the python-frida_12.0.7-1.ubuntu-bionic_amd64.deb package but it didn't work so now I installed using pip install -U frida-tools

Output on my terminal :

$uname -a
Linux kali 4.15.0-kali2-amd64 #1 SMP Debian 4.15.11-1kali1 (2018-03-21) x86_64 GNU/Linux

$frida --version
12.0.7
$frida-ps --version
12.0.7
$frida-trace --version
12.0.7

$ frida -U --no-pause -f net.one97.paytm

Output on my mobile

Problems

1. Unable to attach to any process
2. Unable to spawn any process
3. Once spawned command is issued, device just hangs and have to remove the battery to restart ( thank god I didn't have those irreplaceable battery mobiles )

Only thing that works is frida-ps -Uai

P.S.
I am using frida-server-12.0.7-android-arm64 on my device.
Thanks.
