[CURRENT ISSUE] Sims 4 Unable to Start, Game Data Missing or Damaged

For the last week I have repaired, uninstalled and reinstalled The SIms 4 along with all DLCs multiple times and it still won't launch. I've tried downloading just the base game, no DLCs and tried to launch - still showing the same error: 'Unable to start: Cannot start because game data is missing or damaged. If you have Mods installed please remove them and try again. If not, please repair or reinstall the game via Origin. [de4ee14f:29f00e76:00000000:4b0d852b]'

 There are no mods on my PC and have absolutely no idea how to fix this. I have also uninstalled and reinstalled the EA app which also has not worked. I bought new packs in the sale and I haven't been able to try them out yet. I am currently installing the base game via Steam to see if that works and launches, otherwise I'm going to lose my mind.
