I'm also having this issue on HyperOS stable 1.0.12.0 on DITING device.
However, I think this started when I flashed the boot with magisk so I'm not even gonna bother reporting it to the devs for now.
I can live with the occasional pop-up message every now and then, hopefully next update fixes it.
I've also tried the usual methods of cleaning cache and stuff from that mi secure services thing but it didn't fix it.
