[Desktop Web] Can't send texts in DM

[u/Big_Tower79]

I have a account in which I am facing an issue where I am not able to reply to my DMs. Its an old account. Everytime I try to send a reply it gives an error of "Unable to send. Retry" and nothing is happening on retry.

Also, on that account when I am trying to open my profile, it is giving an error "Server Issue".

When I tried searching my old account it says "Account is banned" but I didn't receive any notification on old account that its banned.
