I had the same issue. What I did was create a new emuMMC. I was then able to boot without getting the yellow screen. The only thing was that my games were missing so I copied and replaced the Nintendo folder from the original emuMMC into the new and everything is back working correctly.
@SylverReZ I've never used a disposable, seems like a waste. kinda cool idea tho. It would be nice to have vape built in to a cell phone even. "The iVape"
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
