Default [Q] Horrific Internal Memory Error! Need help

I can't believe what's going on. It's as if my internal memory is unreadable. Can't save whatsapp chats, can't save SwiftKey layout, can't save XPosed framework, can't play BattleCamp, and other various issues that all have one thing in coming...

INTERNAL MEMORY ACCESS. (whatsapp saves to sdcard/whatsapp, SwiftKey keyboard layouts are on internal memory, xposed is located sdcard/Android/data/)

It's as if my phone has lost access to the memory and everything located on the INTERNAL MEMORY. external memory works fine (music, photos, apps saved on SD card)

Idk what to do now, so stuck been trying hours to fix this... Please ask anything, I'll do the best I can to answer!

Thanks in advance!
