RStudio Pro blank screen after successful login

A few of the users are experiencing blank login screen after successful login attempt.

How do I debug this? I cannot replicate their behaviour as when tried I can login as them without this issue.

We are using RStudio Pro Version 1.2.503 installed on CentOS 7.7 and its a cluster of 3 nodes.

From RStudio Pro admin logs UI, we notice this -
