I haven't found a way yet because of twrp problems, but you can try outjusting some kernel settings and deep sleep options with kernel managers. I recomend SmartPack, free and open source kernel manager avaible on F-droid.

Crashes when trying to install aosp or gsi images, sideload not working, wipeing problems, etc. It is something in the new build, I wasn't getting does on the old build.
Follow this guide and make sure to start with a clean flash first. https://xdaforums.com/t/installing-twrp-and-linageos.4334465/
Don't look at the countury reagons, If the sim card doesn't work after flashing another reagons fimware you have to SIM unlock you phone.
You still need to find fimware with the same SW REV value or you will have to go through hell to trick the Rollback prevention (RP)
try changing the date and time to something old, if that doesn't work take software updates and they should apear.
Do you still have the same issue? If you do, try to possibly downgrade fimware. Flashing older fimware will work without unlocking PBL if it's smasung's official fimware. After flashing older fimware OEM unlocking should appear, and you will be able to flash unofficial fimware images after unlocking PBL.

I had the same issue. I managed to fix it by clean flashing the last working firmware. It works now, but it's not rooted, unfortunately. If anyone knows how to root the Galaxy A12 without this problem, please let me know.
