The Sims 4 - Having issues with both initialisation errors and "TS4.exe has encountered a problem and needs to close."

My apologies for starting yet another topic based on this.

On another Mac, I managed to successfully install a makeshift version of The Sims 4 (no DLCs, couldn't change settings, but was already satisfactory) following the exact same steps to the installing Sims 4 guide using Wineskin.

Today, I make the exact same attempt, but it failed.

On all occasions (even after completely starting from scratch and rebuilding the wrappers, and downloading a brand-new rar via G4TW)
The first time I'll launch it, it will always provide a "initialisation error at startup" issue, and will not launch entirely.
All attempts proceeding will open the screen, flash white for a split second, and have the error "TS4.exe has encountered a problem and needs to close." directly after.

(On a side note, during my previous installation of The Sims 4, I remember there being 6 setup(x).cab files, instead of five when I see now? I'm worried my RAR extractor may have had issues or the download or unzipping wasn't complete. Correct me if I'm wrong.)

All help is deeply appreciated.
