Emerge world `icu` conflicts

Hi folks, I have an issue running emerge -uaNDp @world after syncing repositories, I have many conflicts, most critical are the icu related:

Would be removing icu and emerging again helpful?

$ eix -e icu

### -O1 - - - don’t check (/NO) don’t ask (NO/)
# emerge -C dev-libs/icu -O1
# emerge dev-libs/icu:0/76 -O1

### --with-bdeps=y - - - if need
# emerge -uDN --with-bdeps=y @world -pv

Thanks @AlexOmskiy for the tip!
I was able to solve the icu issue. -O1 was indeed useful.
The other conflicts I’ve resolved by using --backtrace=250.
