Just disable Magisk Hide to fix this :

Magisk Manager > Settings >Magisk > Magisk Hide (Toggle Off)

Answer 2

As explained by @gmlime,

Frida and Magisk require Zygote module to spawn processes. Magisk Hide ptraces the zygote module in order to intercept calls, which locks out other apps from doing so, and zygote is needed by Frida to spawn apps and do early hooking.

We can temporarily disable MagiskHide. We can quickly disable it through the command-line using adb. Run

adb shell "su -c magiskhide disable"

And then recheck with your frida command, It should work.
