I hunt in thick MT Griz country every year both solo and with buddies. Just be smart and have the gear you need - bear spray, proper food storage, first aid and communication capabilities. I carry a sidearm.
If you’re unfamiliar with griz and their country, I encourage you to hunt with a buddy if possible. It’s a huge morale boost and should help deter curious predators.
My final bit of advice is to be smart and alert if/when you actually kill something, and especially if it is in the evening. I realize there are always a million variables, but for starters I’d recommend doing your field dressing in an area where you have some visibility, I.e. not a thicket. Consider your options to leave an animal overnight and finish in the morning, depending on weather, hanging, etc. If you do return to an animal, even just on multiple pack trips, be cautious on your return approach(es). Hang meat a good ways away from the gut pile.
Don’t let it freak you out! Have fun, be safe, be smart.
