WeChat app keeps auto-opening on phone unlock

Since this morning, whenever I open and unlock my phone, it buzzes quickly upon unlock and opens the Wechat app, even though I have force closed it and cleared the cache. I have also restarted my phone and tried turning off notifications. Neither has changed the issue. I'm on a Samsung Galaxy S20, have not installed any new apps to my knowledge since this behavior started happening. Googling the issue, a lot of folks mentioned a virus through a blank app causing similar behavior, but I was unable to find it. I ran Kaspersky and it didn't detect a virus. Is this an app setting, a Wechat issue or do I have a virus?
