Welcome!!
I googled your bike and it looks nice. No rider weight listed, but it's an aluminum frame mountain bike with 29" wheels which makes me think this a sturdy bike. There is a section here called Clydesdales/Athenas that is for big riders and they have real experience.

Maybe reach out to the manufacturer and ask what they list as max weight.
