We have worklist access enabled for few users currently in our Oracle EBS 12.1.3 environment and we upgraded to Oracle EBS12.2.12 version in TEST environment. Since then, we are not able to login to these users where worklist access was enabled, and the moment we try to login to these users the application crash and no other users can login until our DBA team brings up the application.
Except for these users (where worklist access is enabled), all the other users are able to login as expected.
We have already created multiple Oracle SRs but unable to find the root cause.
