lakshya I'm sorry to say, I can't assure you anything, like I said before - I've never seen this issue and there are no sever-side logs from this user. Please, do not take anything I say as a true piece of information, as I honestly just make assumptions based on what I know - and there's just a very little context that I can wrap around with the hope to get the issue fixed.
I basically know that there is an error that makes one particular user profile behave weird and that it is most likely a client-side error only, due to there not being any server-side logs, just a couple of console errors which I am not even sure what they mean. That's all I know - which means that I must assume diagnosis and hope that I hit the right solution
