Made a brief start on AC Valhalla's Dawn of Ragnarok expansion last night. I encountered a glitch at the very start, so in case this helps anyone: just a couple of minutes in (cutscenes aside), there's a boss battle, and this guy was completely thrashing me while I barely took a shaving from his health bar (takes me back to my time with Sekiro...). Anyway, after a few more thrashings, I paused and checked the menu to find that all the various difficulty settings had been maxed out, even though I'd chosen the default/recommended settings. As I was in combat, it wouldn't let me change them, so I restarted the game and again made sure the settings were OK (they weren't) before entering the fight, which was now very straightforward. So if you're finding the gameplay to be much tougher (or easier) than you'd expect, it may be worth checking that the gameplay settings do line up with what you've originally chosen.
