CK3 refusing to launch and keeps giving me an error, help appreciated

[CodedPandi]

So firstly, I did mod the game before the error started but have since done multiple full uninstalls and clean installs to make sure no trace of mods were left on the system
For the past few days everytime I try to run the game, I get to the CK logo and then the game crashes with the error
"[E][pdx_localize.cpp:279]: Duplicate localization key. Key 'APPLY' is defined in both 'localization/english/core_l_english.yml' and 'localization/settings/settings_l_english.yml'."
I've found both instances of APPLY mentioned in the error, but removing either or changing in any way doesnt fix the error and let the game launch. Any help would be greatly appreciated
