Tyche_Lotus Please remove your entire Mods folder, and your ConfigOverride folder within in the same Sims 4 folder, and try starting yet another new save. If it works, the issue might be in either folder, or each one might have a problem file.
If you get endless loading again, move out the entire Sims 4 folder and try again.
If that doesn't work either, please provide a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
