Intermittent SB2040 (CAN) shutdown

I've been running Fysetc Spider V2.2 + Extender (USB-CAN host) with Mellow Fly SB2040 without issue for a year; since the V12 update, I've encountered situations where the printer would shut down during mid print. Firmware reset does not restart the printer, but reboot on the OS does. Looking at the Klipper log shows timeout with the SB2040. Is there anyone facing a similar issue with V12 Klipper?
