The lookup function worked well before I updated to the new MacOS "Big Sur", and I didn't change any setting of it. How should I do to fix that? (Btw, it's also not working after I changed to "Force Click with one finger")

I've just run into a similar problem myself.
It took me a while to work this out, but it looks like the "three finger lookup" conflicts with Accessibility Zoom feature (aka three finger double-tap), if that is enabled.
For me, "three finger lookup" started working perfectly as soon as I've disabled:
Accessibility > Zoom > Advanced > Controls > Use trackpad gesture to zoom

Hello black169.
Thanks for reaching out to Apple Support Communities. We understand that Look Up feature has stopped working on your Mac since updating the macOS. We will be glad to assist.
Let's try safe mode to see if that resolves this. How to use safe mode on your Mac
Cheers.
The three-finger lookup works just fine in my Big Sur installation. You can also use control+command+D when hovering over a word and get the same result.
Hi,
I have the same problem. It seems like it works only on Safari but not on any of other apps, like Chrome or PDF viewers. I don't have an answer for your problem, but just wanted to provide more details about the issue.
