I don't know how to add reference or use libs for fix this error. Please help me to fix this problem
Thank you very much

Depends on what the theme is doing
The theme needs to be upgraded for v4.3
Check with the developer maybe it is this one https://www.nopcommerce.com/en/nopaccelerate-noble-theme

I have the same problem. Did the OP resolve this?

+1.
Does anyone have a link to any useful documentation for theme updates? What I can find is about as informative as saying "it depends on theme".

Simply the theme version needs to match the version of nopCommerce.
If it does and you still have issues then contact the developer / seller of the theme
