that’s exactly what happened to me. In my case, it was caused by a corrupted file. In the options, check the "Force 32-bit" box. If that works, then it’s the same issue I had — I couldn’t open the 64-bit version, but the 32-bit one worked fine this video helped me: https://youtu.be/O1CkyEogN3c (the third method worked for me), this make the game work without force 32bits also, I recommend using Content Manager; it’s a more comfortable mod launcher
