Bad marshal data

General Discussion

Basic Information:

Printer Model: DIY
MCU / Printerboard: Raspberry Pi 3B + MKS Gen L v1 board
klippy_latest.log (14.7 KB)

Issue:
Getting an error after latest update
Internal error during connect: bad marshal data (unknown type code)

The problem seems to be during loading a python sub module (virtual_sdcard.py), the printer worked without issues before update with restart.

Tried pip update/uninstall/reinstall of jinja2 but same issue.
Tried re-compiling and re-flashing board.

Double checked that virtual sd-card (the module that seems to be borked) had full access to the folder.

Not really sure what to try more other than a full reinstall, but would like to avoid it.

Solved it
I rebuilt the python3-env and klipper-env and the error went away.

Hopefully if someone else gets a similar problem this cuts their time in finding a solution
