What is this unknown app on Oppo running Android 11?

This app just popped up on my Oppo A74 running Android version 11 and I can't open it, and it doesn't have a name. I haven't downloaded anything today, and this app only came a few hours ago, so there's no chance of it being an app whose icon the developer forgot to put in. I am also not using an external SD card. I can move it around while holding but I can't delete it nor remove it from the home screen. Clicking it gives the following prompt "Failed to read app data. Cannot run the app". When I long-press it, only app info comes up, clicking that does nothing, it doesn't show any info. What is this app? Is it safe?
