I tried all different available versions of the PAD and Extension and nothing helped. I followed the guide you linked step by step, tried reinstalling everything and still no success.
The problem appeared, when Chrome browser updated to new version (v113). I had PAD 2.26 at that time and before the update, everything was working fine. After Chrome updated, the same flows that worked a few minutes before update, started to fail with error:
Problem while executing action 'ExtractList'. Failed to extract data (web page error while extracting data).

Same error is thrown on different elements using different actions (Click link on web page, Wait for web page content,...)
I tried bypassing this by executing JS scripts, but I always get [object Object] as result. I also tried different browsers and nothing helped.
