what happened to my avatar

Hello sorry for using google translate if there is any error please forgive me, hello the second time I want to ask a question about my avatar I don't understand why my avatar can't be edited I know there are 2 main reasons why my avatar can't be edited 1 is server system error and being penalized on the account but the server system error is not reasonable so it is highly likely that I have been penalized on my chess.com account but the last time my account was penalized was about 1 year ago I noted that I have only been penalized 2 times for speaking carelessly but for nearly 1 year I have not shown any signs and have not violated the terms of chess.com and this is my account: thanhkty hope you reconsider

are you sure u can't edit ur avatar? like really sure???

chess.com said I had no right to edit the photo even though it didn't violate anything
