It could be low temp problem. Increase 10 Degrees and check.
Also you can increase first layer extrution width to 200%.
Use Raft, Because its easy to peel off prints.
@citybird check board workings with usb serial connection with pc . if board is not connecting there is the issue with main board, not display.
If so, upload this firmware : Ender-3 V2_32bit_ 2.0.1V Latest Firmware_0814.rar from https://www.creality.com/download
but rename firmware .bin file to random name every time you upload this file. Because the board does not upload same file name.
Check if it works.
When does this error comes, before auto home?
