Instant pot lid sticking

After trying to force the lever to open our 14 in 1 Instant Pot multi cooker, the release mechanism isn’t functioning properly. The reason for it not opening was that the pressure lock out valve was stuck in the lock position.

I’m imagining that it should be an easy fix if only I could access the top of lid.

Does/ has  anyone successfully removed the top from one of these, Youtube and Google not being very helpful.

I read that as “Instant pot lid licking” and thought this was about licking the lid of a pot noodle when you opened it.
