need some help

I have installed FRIDA's CLI tools and NodeJS. I can successfully get the output by using frida-ps -U. Following the instructions, I started frida-server and then executed rms. I opened http://127.0.0.1:5000/ in my browser, and the page appeared correctly, showing the device information. However, when I start RMS, the left side displays
"com.android.systemui is NOT available on your device!

FRIDA crashed
Error: Command failed: 99".
Additionally, my phone keeps showing "waiting for debugger".
How can I solve this problem?
I tried editing the /config/config.json file to set com.android.settings as the default package, but it didn't solve the problem.
The phone I'm using is Pixel XL with Android version 7.1.2, and I have rooted it using Magisk.
