white background and laggy mac

MacBook Pro 13" (2016) OCLP 2.1.2 Sonoma 14.7.1

i accidentally left my mac running last night while i was playing around with virtualbox and while i was sleeping the battery died

now my mac looks pretty normal when i turn it on, then i log in and that is what i see

if i open apps it goes a bit slow but eventually it seems at all be working kinda okay??

i did try reset smc and nvram, i also tried changing the wallpaper and for a second after i rested my mac it did show the new wallpaper, but it was just a moment

also, the background goes black before turning white

i've tried root patching, 1. all applicable patches are already installed 2. if i try root patching anyway i can't because in system settings i have available the sequoia update (not gonna update anytime soon btw, especially not from the system settings)

any ideas??
