Extreme Lag even with Mods/CC Removed

@Simplycoya  Your computer is more than powerful enough to run Sims 4 on ultra graphics settings at much higher framerates than what you're seeing.  Recording your play will increase the demands on your hardware, but it's still capable of much better performance.

Please try playing a new save in a clean user folder.  I realize you've removed most of the possibly problematic files from the user folder already, but this is just a bit more thorough.  Move the Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and the game will spawn a new folder when you launch it.  Don't add anything to the new folder yet; just start that new save and see how it runs.  Don't download your existing household from the Gallery either; just use a freshly created sim.

Please test without any other software running, only Origin and Sims 4, at least for now.  If fps is still low, restart your computer and try again (with another clean folder), except this time, play while offline.  You can sign into Origin and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.
