I don't think it's an issue with the ROM. you need to flash firmware including CP. also note the different builds:

Samsung Sensor (s3ve3gjv)
Sony Sensor (s3ve3gxx)
Dual Sim (s3ve3gds)

    * 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.


    here you can find my really beta build for our good S3 Neo,

    Thank you so much. It worked.

    I didn't stall the whole stock firmware tho. I flashed everything except system.ext4, cache.ext4 and hidden.ext4 files. After that I wiped everything in TWRP and did a fresh install of LineageOS 19. It worked without any problem. Thank you so much for putting me on the right path. You enlightened me about difference between firmwares and just android ROMs.

    And android 12 feels so much smoother than 10. I honestly wasn't expecting this. Have a good day everyone 😊
