Failed to spawn: unable to find process with name '<full_name_of_the_app>'
This is probably one of the most basic issue, and I'm myself a basic guy :1st_place_medal:
I'm trying to trace functions with frida-trace <full_name_of_the_app> but it outputs Failed to spawn: unable to find process with name '<full_name_of_the_app>' .
Now the funny thing is that running frida-ps -Ua shows this App running. I also tried providing PID, but it also fails.
The frida-agent is running accordingly (I think):

Maybe you can try --attach-pid=21038 which works for me.
Tried. frida-trace com.an.biometric.sample --attach-pid=xxxxx this command not working.
this changed to

You need to write
frida-trace.exe -U -N com.evozi.deviceid --attach-pid=4108
