Maybe it didn't turn in place. The solution is to turn it into place.
If the lid of the pressure cooker can't be opened due to high temperature, it needs to be cooled before removing the pressure limiting valve, then hold the pressure cooker handle and turn it forcibly left and right to open it. If it can't rotate, you need to find out if there is a gap around the cover. If yes, use chopsticks to push down the live nail inserted above the handle, and the pressure cooker will open.
Pay attention to the need to put the pressure cooker in a bright place when operating, and put it as high as possible, so that it can be seen or nailed at a high place, and the overall operation is simpler and easier.
