Solution

Restore yarn.lock file and add package one by one to check which package is causing issue

I restored yarn.lock file and started updating packages and found out that upgrading typescript package from 4.6.2 to 5.0.4 is causes above issue. I have not figuredexact root issue but downgrading typescript to 4.6.2 works
