You can use this useful tutorial on how to properly morph your Character into the rig that you want. It’s important to note that it must have the basic humanoid properties or names but the video explains it well and gives you an example.
Apparently, torsos in rigs cannot be union operations, which is why it kept respawning me (in my personal situation). So to counter this, I have rigged a dummy inside the rig and made it invisible so the torso is technically a part. It is fixed now. Thanks to everyone that replied to this post!
