If your bars are alloy it might be the bars itself corroding into Aluminum-Oxide from your sweat and salt

That’s salt corrosion from your sweaty hands. Best to clean it every now and then. It can put holes in ur bars if it stays there long enough

It looks just like a stuck seatpost – the aluminium oxide is bigger than the aluminium it oxidises into, wedging the part. I’ve seen bars corrode to holy nothing on turbo-trainer bikes but never on a flat bar bike. Does it get trainer use or are you blessed with acrid sweat?

Sweat. Corrosion. You, my good sir, are a heavy sweater. Wash your bike with water more frequently, and remove your grips and clean the bars underneath more frequently.
I can already hear the comments “never use water on your bike, you’ll wash the dirt into the bearings, wash the grease out, and everything will rust, crumble, and blow away”. No. Your bearings are sealed pretty good. Clean water doesn’t rust anything. Water is the only way to wash sweat and corrosion from all the cracks and crevices that a rag can’t get to.
