Same issue here:

I uninstalled StepD and it is still shown under Plugins. I think that there is the problem. But I don´t know where to get rid of it.

I deleted my .octoprint folder and gave it a fresh start. that solved the problem for me.

/home/pi/.octoprint/data/stepd/stepd seems to be missing.

Is golang installed on your Pi?

You can install it with

sudo apt install golang

If the golang package was missing, uninstall the StepD plugin, clean data and reinstall again for it to rebuild the binary.

Did a fresh install using pi imager. Installed Golang. Ran the zip file in the plugin installer. Did this twice. Still getting a ValueError: 'I/O operation on closed file' @ comm.py:_readline:3940 error as well.

Specifically:

Unexpected error while reading serial port, please consult octoprint.log for details: ValueError: 'I/O operation on closed file' @ comm.py:_readline:3940 Changing monitoring state from "Operational" to "Offline after error" Connection closed, closing down monitor

It will connect, handshake/echo a reply from an M503 then pop out of connection.

Once I turn the StepDaemon plugin off, everything is fine. I see this is different from the first post here but it's related to a comm.py serial issue I believe. Maybe not stepD code, but code that it depended on that broke something in an update?
