I believe you might need to go a lot lighter and incorporate a lot more recovery into your routine until you adapt.
I’m older than you but I know some things to be true for me, and maybe you’ll recognize them as well.
If you’re having night sweats, your sleep is absolutely shit. I have to be on HRT or I can not sleep. If I’m having constant hot flashes all day I’m also cranky AF.
You may not have the same running fitness as you did, but that doesn’t mean you can’t get there. Run slower, take a walk pause every so often and walk 5-10 steps and then return to running. Your body may need a little more time to adapt to running outdoors.

If you can still get them, get a big bowl of halloween give away candy’s and give those out.
