I Got a Compromised Account Warning on Instagram and Cant Refresh Feed

For the past day, the feed on my Instagram account, which I use on my Redmi Note 8 phone, hasn’t been refreshing, and I keep receiving a warning saying “your account has been compromised.” This is the first time I’ve encountered such an issue. I suspect it might be because I sent too many follow requests. I updated the app and tried again, but the problem still persists. There are no paid transactions or purchases associated with my account. I haven’t contacted Instagram customer service yet, but I’m requesting that my account be reactivated and that I receive a detailed explanation about the issue.
