SSD is fine. Checked on another device.

On this device it boots up with a question mark folder - but if i plug in a bootable macos installer i get the apple logo and loading bar and it boots up.

Even when its flashing the Question makr folder and insert the installer within 1-3 seconds - i get the apple logo and device boots up normally.

I entered disk utility and did first aid. But still the same.

I have installed MacOS via external disk. Issue seems fine for now. I will update if issue re-appears will let you know.
