After the account was upgraded to Cairo 1.0, the owner was maliciously changed

After I upgraded to Cairo 1.0 with argent-x, I was maliciously modified as owner, causing me to lose control. How to deal with this? I think this is a malicious function. Why can the owner of a personal account be changed? And the new owner does not exist, I think this is an argent-x problem。The official team is requested to pay attention to this issue
