Your 2080 should work, I played this previously on my Lenovo Legion Y520 laptop, back before September, which had a 2060. The only problems I ever had was overheating and excessive fan noise, which is why I would always stop playing and give it a rest every hour and half.
I'm now playing on actual gaming PC now.
... So either laptops can't handle the newer updates (which I haven't tested yet as of typing this), or maybe your laptop is lacking the proper specs elsewhere? If you list your laptops specs people that are smarter than me may be able to help you.

Sorry I can't actually give better advice, good luck.
