Okay. So I read that the north sentilese tribe numbers about 50-100. Amongst them and other uncontacted tribes, I don’t believe they have major genetic issues from inbreeding, how is this possible? Or am I mistaken and they have major inbreeding health issues?

One thing to consider is that for an isolated population living entirely off the land, then many of the physical abnormalities resulting from inbreeding would in theory work themselves out. Kids born with misshapen faces or malformed limbs for example very might not live to adulthood and even if they did, they would be less able to reproduce themselves. It’s one thing when your child is heir to the throne and you are the king, then you can tell your son’s sister, niece, aunt, cousin, whatever “no you ARE marrying him, and you ARE having kids!”
For internal illnesses such as hemophilia and schizophrenia, those very well might affect greater percentages of the population. But without being able to do more in depth studies, it’s really impossible to know.
