1. In my case I already created a new account and applied again with the same PCC along with the replies from Embassy and Korean police that Lapsed records can not be provided and PCC should work. And it worked for me.
2. IRCC realized their mistake and wanted to reopen my case but I received another ITA on my new profile so I skipped it.
3. My case was rejected on the 29th, of June 2022 but on 1 July 2022 IRCC on the website removed the conditions of the Lapsed record requirement. And now they require PCC along with a written Self-declaration which can be done on an A4 page but I did it on a Stamp paper and notirised it. So that's how it should be onwards.
So all you need is the PCC and the self-declaration and that should work.
