Hello Girija,
thatnk you for the logs, I am now able to see and examine them.
It appears that your model is not listed among the compatible RPi4 boards here on our manual: Technical Specifications — Instructions on Setting Up Your Raspberry Shake so that could be the cause.
Many other users have used a RPi4 without issues, so we know that for those modules the Shake OS performs as expected.
However, we also have had other users with your same issue of the rs.local page not populating correctly. You can try a solution that my colleague has shown last week, here: Stuck on config screen - #6 by ivor
