  1. Please do not hijack topics.
  2. You hijacked a topic in the IDE 2.x section of the forum and your information clearly showed that you're using IDE 1.8.19.

For these reasons I have a split your question to a new topic.

Not sure if I can help but does your Nano indeed has an ATmega168 and not an ATmega328P? Try the different options under tools/processor and see if one of them works.
