You have a touchscreen laptop and that icon there shows up for you to click it and enter your bitlocker PIN code. This is probably being triggered because TPM has been provisioned and/or bitlocker is active
Hi and thank you for making me touch it. ;D It goes into recovery handing out a nice 0xc0000225, which usually means "cant access bootdevice" and comes with various files, but here its "\hiberfil.sys" I can then touch languages or Esc on the display to end up in the UEFI BIOS. Hmmmmmmm...rebooting does show the icon again, but takes me back into WIndows 11 as usual. *phew*
