running out of space

[Android Central Question]

I have a Samsung A30, I am located on a military base with no access to a computer so I can't flash to a stock rom, but I need to do the best to solve this problem:

I have to reset my phone every few hours, when I power it on it shows 40Gb free, after 1 or 2 hours it shows 30Gb free and after a couple hours it runs out of space.

Developer options are enabled on this phone, OEM Unlocking, USB debugging, verify apps over USB and multiple PBAP Properties.

Also, Magisk Manager is installed.

What could be causing it or what could be filling up my space?

If you have a SD card , take it out possible can be failing causing this issue, also it's not stock anymore so this can be the issue also.

Welcome to Android Central! I assume this is the 64 GB version of the A30, and not the 32 GB version, right?

Which custom ROM is installed right now, and how long has it been on the phone? How long has this problem been happening?
