Rooting FP4 /e/os with Magisk

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!

Edit:
Apparently, it works for other. I got a patched boot img from someone where it worked. So for me the problem is solved. Odd tho, after all.

I’m having the exact same issue with my FP4 over here. has anyone figured out the solution?

edit: I also tried using TWRP from this link

to flash Magisk.zip and get root that way, but fastboot boot twrp.img causes it to get stuck on a boot screen so it doesn’t seem to be the way to go, sadly.

Did you both try this method? PLEASE DO NOT FLASH THE BOOT! JUST BOOT

I am currently on iodéOS for Fairphone 4 and sadly stuck on the start-logo when I try to boot the magisk-patched-boot.img
