This happened to be in No Man's Sky. Somewhere close to release, after being stuck in the eternal loading screen where the stars are whizzing by, a white screen with a circle in the bottom appeared. Thought it was another loading screen, but apparently the letter 'E' was hidden in the circle, which you needed to hold. Felt embarrassed when I got past the white screen...
This happened relatively frequently to me in Horizon Forbidden West. The PS5 is done loading almost immediately but lets me sit on the loading screen like a dummy.
This is me with League of Legends, I'm sure it's been about 7 years since they made it so you need to press 2 buttons to queue for your next game and I still only hit 1 and sit there like a chump
