Time will tell.

New tyre only 300 miles ? I assume recently fitted then ?

If so the tyre monkey has caught the inner seal with the lever or the nasty air tool bead breaker, I've had the same & they don't admit catching it - you just find a slow puncture a few days later banghead

You may struggle to get a good seal from a patch-up as silicone does not stick well to existing, I had to grind out all the split area
