As a new runner, your heart rate will be really high. Unless you have some notable cardiac risk it's not a big deal.

Ignore the zone 2 messaging for now. Zone 2 training is basically useless for getting better at running when you're just starting because a new runner staying in zone 2 is just walking. You need to run to get better at running. For now, just ignore heart rate and focus on how you feel. Do run/walk and gradually work on increasing the time you run before you stop to walk.

PS.

"Zone 2", “80/20" and the like is advice that's really meant for intermediate runners starting to train more seriously and it basically just means "it's better to run easy most of the time so you can run more, and so when you do run hard you can get full benefit because you're not already exhausted. "

It is good advice in context but has been spouted without context by so many running youtubers and influencers that it has probably done more harm than good.
