UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

After the last update to 2024-01-03 12:21:20 +0100 [06bcf54f9] my wb is no more working - charging is never started. Digging in the logs I found this in the main log:

And this

I have a OpenWb Duo with a 3P/1P setup like this:

It looks like the cp0 (i guess this is charging point 0?) is no more found or mounted faulty. I didn't change anything on my openWb the last weeks and this error started after the upgrade to the 2024-01-03 12:21:20 +0100 [06bcf54f9] release
