Shahrukh Khan and Salman Khan had reportedly worked together in the film “Karan Arjun” in 1995, which was directed by Rakesh Roshan. However, it was in the film “Kuch Kuch Hota Hai” in 1998 that they appeared in a full-fledged film together, in which they played significant roles.

As for why they haven’t worked together since then, there have been various reports and speculations about the reason. Some reports suggest that there have been creative differences and personal issues between them. However, both actors have publicly expressed their respect and admiration for each other

and have even appeared on each other’s television shows and events. It is possible that they haven’t found a suitable project that interests them both, or it could simply be a matter of scheduling conflicts.
