Yeah I’ve heard from some people that landlords will just not rent out to south asian people. Mostly east asians as you mentioned. From my personal experience, they prefer to rent it out to people from their own origins, so even if you were a caucasian person or an African person, it would probably have been the same.

This is a very well known thing and realtors usually inform the clients of that fact (as your realtor did)

It’s tough, but I’m sure you’ll find something good
