FP4 Root Access is possible, maybe a bit risky

Hey!
I tried to root my FP4 on /e/os using Magisk.
It worked using the default stock rom on FP4, so rooting the device works.
However, using /e/os Magisk just crashes when I try to modify the boot.img using the install button in Magisk.

This happens with v23 and the canary build. Does anyone have an idea how to fix it? Could it be any permission issue?

Cheers!
