I have an older instant pot pressure cooker (ip-lux50 v3) and I've tried making rice according to various recipes I've found on the internet and none of them have turned out well

This is one recipe I've tried

The rice came out gummy and stuck to the pot. I'm hoping for suggestions of a way to make good rice based on this recipe
