EDIMAX SP2101W - not working with firmware 3.0.0c

Hi to everybody reading this,

I loaded HA on my Raspi 3 and configured my EDIMAX SP2101W. But it seems there is an error interpreting the return messages from the switch. Therefore I cannot see the switch an cannot turn it on or off.
I am using:
Home Assistant 2022.12.6 Supervisor 2022.11.2 Operating System 9.4 Frontend 20221213.0 - latest.
The SP2101W is updated to the latest Firmware 3.0.0c
I am new to Home Assistant and have not used it before. So I do not know if it would have worked with the previous firmware. Could someone tell me how to look at the source code? The directories mentioned in the log are empty on my Raspi 3 installation.
Here is the error log:

Hello. I am having the same issues. Were you able to fix this?

I have the same Problem. I am not able to connect to the edimax Switch with 3.00c Firmware.

SMA had also problems with V3 as it was releases, but they fixed it.
