Server Error (500): after account changes (renaming)

Hi, a long time ago I renamed my Salsa account from iikrllx to krekhov, but only now I noticed that my personal page still links to the old address (https://contributors.debian.org/contributor/iikrllx@salsa/), I tried to change it myself and broke my account, now when I log into my account I get: Server Error (500)

Here are my steps to log into the account:

https://contributors.debian.org/signon/login/

Salsa -> krekhov -> Password -> Redirecting -> Server Error (500)

Could you help me? Please.

I would like iikrllx to no longer be used, and all contributions to be visible to krekhov, is it possible?

I see a similar issue here: #28 (closed), but mine is probably more complex.
