Can't write to system

[ummi412]

Hey all I'm running into a bit of a snag and can't seem to work my way out of it so I thought I'd get some help.
So anyways I wanna modify mixer_paths_tasha under /system/vender/etc but whenever I do (using solid explorer) it just shows up the red x and says unable to modify. I tried using different file explorers all to the same effect. Tried using terminal emulator and it says "no space left on device" and solid explorer shows root at 0b free. I've already checked and system is mounted as R/W and if I try to copy a dummy xml with gibberish text it'll copy it but wipe it clean.
I'm running OxygenOS 9.0.5 and used magisk to root. I have already reset it to factory defaults and flashed OOS multiple times but the problem remains.
Any help would be greatly appreciated.

Since you're already using Magisk, instead of trying to manually modify the system partition, you could create a local Magisk module that uses the modified file you want.

You can read the documentation here: https://topjohnwu.github.io/Magisk/guides.html which has the link to the module template in the Magisk Module Installer section.
Pay close attention to the first bullet point under that section since you would be creating a local module.
Your modified mixer path file goes in system/vender/etc in the module.
Have fun.
