shiningjs4u That's great that it worked—it means the issue is something in your old user folder. Move over the saves folder first, and if you get the same issue, remove that folder and try one save at a time. (Launching the game should create a new, empty saves folder.) It's possible you have this issue:
Crashes on Mainmenu | EA Forums - 12139111
If you find that one or more of your saves are broken, try the suggestions in that thread.
If your saves are fine, test the contents of the Mods folder next; I know you said you removed your mods already, but one or more of them could be broken still while you also have another issue. The 50/50 method can help make the process more efficient if you have a lot of mods and custom content.

Once you've sorted through your mods, you can move over the contents of Tray, plus Screenshots and Recorded Videos if you care about those. The rest can be discarded.
