Guix System Thread not running

I am using e2stuido 2023-10 Guix 6.3.0

Guix System Thread running for 7 times and stops. other threads continue to work.

If I send KeyDown events, Message Queue is getting full

Stack Tab not showing anything

GUIX System Thread Stack. It is waiting for Semaphore.

window1_handler not receiving Touch Events. Touch Events are sent by callback functions.

window1_handler gets two events at start up. Got focus and Show Window events.

subsequent events are not receiving.
