Samsung Galaxy A20
Guys please help, I have a lot of problems here, I can't install apps from google play it says no enough space or even download files from chrome, I can't use the camera.

I don't know where is the problem, I think it is from installation I wiped data then installed, then wiped data and dalvik, everything is not working even the settings, please help.
The stock ROM version before I installed was A202FXXU3CUE8.

    This is a small project based on AOSP. We try to be a platform for beginners and support the Custom ROM community with our own unique contributions as well. This ROM exists thanks to inspiration of AOSiP, Thank you! #StayDerped

    Code: 
    /* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

    GApps included!

    What's broken?
    - VoLTE (This depends on Samsung Frameworks)
    - Netflix HD (DRM Widevine)
    - On some a20e devices, NFC is dead. (Will be fixed on next release)

    March SPL is delayed because there is no Android 12 with March SPL, but there is Android 12L now. Derp main dev is WIP merging now, will build after he finishes merge as soon as possible.

    Derp is dead, dev deleted the source. The eureka team said that only some roms would be coming out on this month. Ancient is dead for a20 probably so the only official 12.1 rom we have for a20 is Spark OS
