My Processes under Activity Guide Composer is forcing a user logout even with Security rights

Current Env: PT 8.60.13 / HCM PUM47.

We recently applied a change package from HSPUM53 with some Onboarding related fixes. After we applied the change package from HSPUM53/PT8.62 to our current env, when we tested Onboarding AG with My Processes page, it forces a user logout of PIA. This was not happening before we applied the change package from HSPUM53. So wondering why this strange behavior.

I checked the AG Composer & other security setup:

AG Composer Categories > ONBOARDING > Security (Tab) - Security access ( OnBoarding Administrator for both Admin category & Add Template)

AG Composer Tempalte > (selected template) > Security section - Has all the necessary roles (OnBoarding Administrator, OnBoarding Employee (End User).
