[Magisk] ~clumsy~:
I have been experiencing a boot issue when changing my device fingerprint. I have attached my propsconf.log log below. Basically my phone doesn't boot, gets stuck on the boot animation. However, if I revert the fingerprint settings using ADB shell and root it boots fine.

I noticed in the propsconf.log there are some segmentation faults.

Other things to note I am using Busybox as suggested. If there is anything else I can get let me know, I tried to get Magisk but there doesn't seem to be anything in /data/cache/* when it happens.

cat /data/cache/propsconf.log
