java.lang.NullPointerException occurs due to a situation in application code where an uninitialized object is attempted to be accessed or modified, meaning that you might have removed a mod which had an entity attatched to the player and now the game can't load in said entity because it doesnt exist, since its value is "null"(=nothing), resulting in a crash.
I've had this problem as well, but mine had to do with the graphics rendering program OpenGL. Usually this error code is caused by incompatible mods, mods made for a different version of minecraft, or two or more mods that are each made for a different version. (My error was the third, and I fixed it by removing my mods and installing the respective minecraft version they were made for.)
Some things with mods do this. It's hard to find them in big groups, though. Your best bet is to try removing one mod and adding it back in when you remove the next one.
Is that the entire error?
Can you give me the crash log?
