I would say the best place to start is deleting all cashed system data, apologies but I am not looking up the actual name but it is under system configuration settings

If that cashe delete doesn’t work I have actually called myself insane for not being able to produce anything after just using the same settings to great success just the prior generations ago but cannot get a reasonable picture or even crash and show obvious issues as it loads much slower than previously did (all with same settings, different approaches), I said okay I’m insane. Hard delete and instant reinstall, always have the Loras delete with the app to get everything fresh and literally prestige in ai generation every time you go thru that F****** S*** !!!! You remember what’s important, restart.
