please help

First, for the sake of whatever gods: Is it so damned difficult to follow the directions and provide a klippy.log? Do the directions need to be in red and blinking, or what is the issue?

Second, check if you are affected by: Debian Bullseye Bug causing Klipper to no longer find the printer board

sry forgot
i just updated it

Issue a sudo service klipper restart followed by a firmware restart via the webinterface, due to mcu.error: Can not update MCU 'BTT_CAN' config as it is shutdown
Apart from this, nothing special in this log you provided.
