No games working? (unmapped memory?)

Hi all! Before i get started just wanted to say all replies are GREATLY appreciated, Thanks so much! So about 3 days ago i decided to install RPCS3 for the first time. And from my first experiences with it everything worked perfect it was amazing i was so impressed. Rock band worked out of the box with my guitar and drums, demon souls ran great but after a day or two it just stopped working entirely for every game. Basically the only thing i changed in the settings since it worked out of box was the game config for rock-band 1-3 so that way i could fix a minor visual bug where the in game characters we're solid black. And that seemed to fix it for that day but after that literally every game just stopped working and kept giving me errors. Out of desperation to fix this i tried downgrading the versions of RPCS3 which didn't work. I tried installing different updates of PS3 interfaces this also didn't help.. And I've also tried messing around with some "known" fixes in terms of settings and what not for RPCS3 to no help at all. The strangest thing about this since everything worked out of the box for me is before i even started trying all these methods the only factor that changed in terms of what i was doing compared to the usual was me changing 1 setting (adding "write color buffers" checked under GPU in custom boot configuration)  for specifically my rock-band games because of the visual bug. And me adding more games i had backed up from my console. I'm gonna leave my log files packed up below in a .7z file. Hopefully you guys can help me figure this out. Thank you guys so much for all of your hard work on the RPCS3 project!
