Klipper not booting

Basic Information:

Printer Model: Ender 3 (not pro but came with v4.2.2 motherboard, wierd.)
MCU / Printerboard: Creality V4.2.2 (With GigaDevice STM clone)
klippy.log (45.5 KB)
Printer.cfg is the example for ender 3 pro but with fluidd.cfg included and added ATSAMD51 board with display as an alternative to the display on-printer.

Describe your issue:

Seems like klipper is not booting, as when using USB serial it just puts some characters i dont understand and when using the lcd connector serial, nothing gets outputted.
Fluidd/Client is stuck on

Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Error configuring printer```
on both.

Looks like nothing is flashing. I will try to reformat my SD.

Seems like my 16 gig SD card does not flash or something, changing it to my 128gig camera sdcard fixed the flashing problem, now just the klipper problem to be fixed.

Okay, now it boots but there is still the serialhdl problem. Even when i switch the primary from the actual mainboard to the ATSAMD custom display mcu, the same error rises.
