It could be you selected TS4.exe instead of TS4_x64.exe (or vice versa) and have to change it in the game properties through Origin (64 recommended, of course) OR you selected the wrong .dll when installing ReShade. One friend of mine installed dxgi.dll (DirectX 10) and it worked, as for another friend it didn’t and just worked when he installed d3d9.dll (DirectX 9). I installed d3d9.dll and it’s working just fine, I also believe 9 is the right one, but I’m not quite sure. You can reinstall ReShade over the current installation, it’ll replace it. Also, you’ll know when it works, as a bar loading the shaders will appear before you can open the menu and the game might freeze when it opens because of that, but it’s completely normal, don’t worry.
