What LVGL version are you using?

v8.0

You need to update lv_examples as well.

I did that all of lvgl v7 files are replaced with v8 and sample folder set to ‘exclude from build’. But the sample folder is not excluded from build after build. I don’t know why it doesn’t work.
Anyway I deleted the sample folder from project then builded successfully.
