CR-10 V2 doesnt connect without safe mode

What is the problem?

Ocotpi cant connect to printer via usb only works when octopi in safe mode

What did you already try to solve it?

i tired downloading GPX plugin 4 different usb cables in all 4 ports in Raspberry pi 4

Have you tried running in safe mode?

yes it works in safe mode but still cant initialize SD Card, i get Warning: Firmware Broken

Did running in safe mode solve the problem?

yes it connected but no SD CARD

not sure how to fix it, or at least make it work in safe mode so that SD card WORKS

Uninstall the GPX plugin, it is definitely not going to work for your printer.

and then what? i did try it without it, before even researching what to do

Because that plugin does not work with your printer and causes OctoPrint to restart in Safe Mode.

Try it without the GPX plugin, and then share a new systeminfo bundle - all the logs you have provided show the GPX plugin getting in the way.

ok i finally got to work on it again, and deleted .ooctoprint folder so it works as fresh install, and it somehow works now? idk why but i still have that firmware error

**Warning: Firmware Broken**

Your printer's firmware is known to have a broken implementation of the communication protocol. This may cause print failures or other annoyances. You'll need to take additional steps for OctoPrint to fully work with it.

usb seesm fine dmesg

here is the new system bundle, it seems teh SD card firmware is broken, is this solvable by updating printers firmware ?
